Z Grills 450A2 vs Traeger Pro 22: Side-by-Side Comparison for Weekend Pitmasters

If you have been shopping for a pellet grill, you have almost certainly looked at both the Z Grills ZPG-450A2 and the Traeger Pro 22. They sit in the same category, run on the same fuel, and both promise set-it-and-forget-it BBQ for the weekend backyard cook. The price difference is the part that stops most people cold. The Traeger Pro 22 runs close to double the cost of the Z Grills 450A2, and you are allowed to wonder whether that premium translates into better meat or just a better-looking nameplate on the front of a very similar machine.

We have cooked on both grills. Ribs, chicken thighs, pork shoulder, a couple of briskets, and one memorable rack of beef back ribs that turned out better than it had any right to. We are not here to tell you Traeger is bad gear, because it is not. We are here to tell you exactly where each grill wins, where it falls short, who should pay the premium, and who is throwing money away by doing so. The short answer is that for most backyard cooks, the Z Grills 450A2 is the smarter buy. Here is the full reasoning behind that call.

Where the Z Grills 450A2 Wins

The clearest win is price, and we are not going to dance around it. At roughly $399, the Z Grills 450A2 leaves you with $250 to $300 in your pocket compared to a new Traeger Pro 22. That is not a rounding error. That is a full season of quality hardwood pellets, a reliable wireless meat thermometer, and a heavy-duty grill cover, all purchased from the savings. For a first pellet grill purchase or a gift for someone who is just getting serious about backyard BBQ, that dollar difference is as real as it gets.

The PID V3.0 controller is a bigger deal than most budget-grill buyers expect. PID stands for proportional-integral-derivative, which is the closed-loop control algorithm that decides how much pellet to feed the auger at any given moment to maintain a set temperature. The result in practice is temperature variance of roughly plus or minus five degrees Fahrenheit during a stable cook in moderate weather. We have logged grate temps on both grills using a third-party dual-probe thermometer over a three-hour low-and-slow session set at 225F on a 72-degree afternoon. The Z Grills 450A2 held tighter than the Traeger Pro 22 on that particular test, which is the opposite of what the price gap would lead you to expect. Neither grill embarrassed itself, but the Z Grills result was a genuine surprise.

The 459 square inches of total cooking space is sufficient for most family cooks. You can stand two full racks of spare ribs upright on the main grate, fit a six-pound pork shoulder flat, or run eight to ten chicken thighs without crowding. We have done full brisket flats in the 10 to 12 pound range without any awkward placement or diagonal angling. If you are cooking for a group of four to six, this grill is not going to feel cramped. The upper rack is real cooking space, not just a warming shelf.

We logged grate temperatures on both grills over a three-hour low-and-slow session. The Z Grills held tighter than the Traeger at 225F. That was the opposite of what we expected going in.

Assembly on the 450A2 runs about 45 minutes to an hour for most people working alone with a Phillips screwdriver. The legs are solid, the hopper lid sits flush with no wobble, and the grease management system drains cleanly into the catch bucket without pooling on the deflector plate. The pellet door on the hopper side closes securely, which matters more than you think when you want to store the grill with pellets still loaded. These are the kinds of details that separate a grill you enjoy using from one you tolerate using.

Where the Traeger Pro 22 Wins

WiFi connectivity is the Traeger Pro 22's real differentiator at this price tier. The built-in WiFIRE system connects the grill to the Traeger app on your phone, letting you monitor pit temperature, set high and low temp alerts, adjust the set point, and track cook history without leaving your house. If your grill sits in the backyard and you are watching a game or putting kids to bed while a brisket runs a 12-hour overnight cook, that remote visibility is worth something real. The Z Grills 450A2 has no WiFi. You add a third-party wireless thermometer to fill that gap, which works well, but it is an extra purchase and an extra app.

Cooking area is the other genuine advantage. The Traeger Pro 22 offers 572 square inches of total cooking space versus 459 on the Z Grills. That extra 113 square inches makes a difference when you are cooking for eight or more people, running two proteins at different temperatures on different racks, or trying to do a full brisket alongside a tray of chicken. If large-group cooking is your regular use case rather than the occasional holiday exception, that space matters. The Traeger also reaches 500F at the top end of its temperature range, giving you a bit more finishing heat if you want to crisp chicken skin or put a sear on a steak after a reverse-sear low cook.

Brand ecosystem and parts availability are worth mentioning for the long-term thinker. Traeger has been building pellet grills since the late 1980s and has a much larger domestic parts network. Replacement igniters, auger motors, grates, and controllers are easy to source through Amazon, hardware stores, or the Traeger site directly. Z Grills has improved its after-sale support considerably over the last three years, but the parts ecosystem is not as deep. If you are someone who likes to fix things yourself and wants assurance that a replacement auger motor is a two-day Amazon order away in five years, Traeger has the edge.

Temperature Accuracy: What the Numbers Actually Show

Temperature control is the single most important performance spec on a pellet grill. It also happens to be the spec that marketing copy distorts the most. Both grills claim precise temperature management. The Z Grills PID V3.0 is a genuine closed-loop algorithm that samples grate temperature and adjusts pellet feed rate continuously, correcting faster when it detects a deviation. The Traeger Pro 22 uses the WiFIRE digital controller, which performs well but has historically shown slightly more variance during cold-weather or windy cooks because the correction algorithm is less aggressive.

In practical terms, both grills are more than accurate enough for barbecue. The meaningful temperature spec for a low-and-slow cook is holding a stable window between 225F and 250F for hours at a time without wild swings. Both of these grills do that reliably in normal backyard conditions. The difference between a 5-degree variance and an 8-degree variance over a 10-hour cook is not going to show up in the finished brisket. The grill that matters less here is almost always the operator, not the controller algorithm. Where genuine accuracy matters most is the first two hours of a long smoke, when smoke ring formation and bark development are happening. Both grills handle that window cleanly.

Hopper Size and Pellet Consumption

The Traeger Pro 22 holds 18 pounds of pellets to the Z Grills' 15 pounds. At a standard low-and-slow consumption rate of 1 to 1.5 pounds per hour at 225F, the Traeger gives you about two to three more hours of unattended run time before a refill is needed. For overnight brisket cooks where you want to wake up to a full hopper rather than an empty one, that margin provides some peace of mind. For most weekend cooks that run 6 to 10 hours, the 15-pound hopper on the Z Grills is adequate without any babysitting.

Both grills run standard food-grade hardwood pellets from any brand. There is no proprietary pellet requirement, no lock-in, and no performance difference between running Traeger brand pellets or Bear Mountain or CookinPellets in either unit. We have used several different brands in the Z Grills 450A2 and found no meaningful difference in temperature stability or smoke flavor profile across quality pellets. Buy whatever is in stock and priced right. The grill does not care.

Who Should Buy Which

Buy the Z Grills ZPG-450A2 if you are purchasing your first pellet grill, if you cook for a household of two to six people on weekends, or if you want the best temperature accuracy per dollar spent anywhere near this price range. The PID V3.0 controller holds temperature as well as or better than grills costing significantly more. The 459 square inches covers every cook most families do more than a few times a year. And the savings over the Traeger are real money that buys real gear.

Buy the Traeger Pro 22 if remote monitoring through a smartphone is important to your cooking style, if you regularly feed eight or more people and need the larger cooking surface, or if long-term parts availability is a deciding factor for you. The premium is real and you should be buying those specific features, not just the brand name.

One honest note: if the WiFi app is the only thing pulling you toward the Traeger, know that a standalone wireless meat thermometer with Bluetooth or WiFi app support runs about $29 and works on any grill. Adding one to the Z Grills 450A2 closes most of the monitoring gap and still leaves you with well over $200 in savings.
