What is identical, and why that matters most
Before the table, the part most comparisons skip: these two cookers work the same way. Pellets drop from a hopper into a fire pot. An igniter rod lights them. A fan feeds the fire and pushes heat and smoke through the barrel. A controller reads a probe in the chamber and speeds the auger up or slows it down to hold the number you dialed in.
That architecture is why both grills are easy for a beginner and why both give a lighter smoke flavor than charcoal or an offset. It is also why the food question has a boring answer. If you cook a pork shoulder at 250°F on each of these grills with the same pellets, you are running the same process twice. Anyone who tells you the brand changes the result is selling you something.
So the real decision is a shopping decision, and it comes down to four things: what is in the box, what the controller does, how long the warranty runs, and what happens when a part fails in year three.
The published specs, side by side
The left column comes from Traeger’s own product page for the Pro 780. The right column comes from the Z Grills listing we link on the card above. Blank is never a guess — where it says not published, the maker does not state it.
| Spec | Traeger Pro 780 | Z Grills 700 series |
|---|
| Cooking area | 780 sq in | 700 sq in on the title; one listing bullet says 697 |
| Temperature range | 165–500°F (maker) | 180–450°F (listing) |
| Controller | D2 with WiFIRE app control | PID, on-grill LCD only — no app, no WiFi |
| Meat probes included | One | Two |
| Hopper | 18 lb | Weight not published; listing claims up to 28 hours of cooking |
| Insulation | Not published | Dual-wall insulated base |
| Cover in the box | Not included | Included |
| Warranty | 3 years | Not published on the listing |
| Weight | 150 lb | Not published on the listing |
| Maker’s list price | $999.99 | Not published on the listing |
Two rows in that table are worth stopping on, because they are the only rows that change what you cook.
The 50°F at the top of the dial
Traeger publishes 165°F to 500°F. The Z Grills listing publishes 180°F to 450°F. The gap at the bottom is irrelevant — nothing you smoke happens at 165°F that cannot happen at 180°F, and USDA’s own smoking guidance puts the chamber between 225°F and 300°F anyway.
The gap at the top is real but narrow. Fifty degrees is the difference between a grill that will put a hard sear on a steak and one that will get it most of the way there. If you want one machine that smokes a brisket on Saturday and cooks burgers hot on Wednesday, the Traeger has a slightly better claim to it. If searing matters a lot to you, honestly, neither of these is the answer — read whether you can really grill on a pellet grill before you spend the money on that assumption.
Neither temperature range tells you anything about smoke flavor, which is the thing people actually expect it to predict. Smoke output on a pellet grill is a function of how often the auger cycles at low temperatures, and no maker publishes that figure.
The hopper rows do not compare, and that is the point
Traeger publishes a hopper in pounds. The Z Grills listing publishes a run time in hours. You cannot convert one to the other honestly, because hours depend on the temperature you cook at and the weather you cook in — which is exactly why we will not print a conversion here.
What you can take from the two claims is that both grills hold enough fuel for an overnight cook, which the cheaper pellet grills on this site do not. Our Pit Boss 440 review exists partly to explain what a five-pound hopper costs you: it is two to five hours, and a brisket is twelve. Both grills on this page clear that bar comfortably. If you want the arithmetic behind pellet consumption, our cost to run a smoker page does it with published burn rates rather than brand claims.
What the extra money actually buys
Strip out the specs that are effectively tied and you are left with three things on the Traeger side of the ledger.
The app. WiFIRE lets you set the temperature and watch the probe from inside the house. On a fourteen-hour cook that is genuinely pleasant, and it is the single feature most Traeger owners say they would miss. It is also a convenience, not a cooking improvement: the Z Grills holds its temperature with a PID controller and shows you both probes on its own screen. You walk outside to read it.
The warranty.Traeger publishes three years. The Z Grills listing publishes no term at all, which is why our card prints “Not published” — and it is the one row in the table where we think the gap is worth real money to a nervous first-time buyer. A pellet grill has moving, electrical parts: an auger motor, a fan, an igniter, a controller. Those are the parts that fail, and a published term tells you who pays. If a warranty matters to you, ask Z Grills for the term in writing before you buy rather than trusting a number you read on a review site.
The network. Traeger is sold in hardware stores all over the country, its pellets sit on the same shelves, and parts for grills made a decade ago are still orderable. That is not nothing when a controller dies in year four. Z Grills sells direct and through retailers, and parts come to you by post.
And on the Z Grills side of the ledger, for less money: a second meat probe, a fitted cover, an insulated base that helps in cold weather cooking, and a PID controller that holds a set temperature as tightly as anything in this price class.
Prices, and the one trap on this page
Both cards above show a live price, because we do not store prices. The trap is Traeger’s own list price: the maker publishes $999.99 for the Pro 780, and the grill is frequently sold for materially less than that. Buying a Pro 780 at full list is the single easiest way to lose this comparison badly — at MSRP you are paying premium-cooker money for a mid-range cooker’s results.
If the two grills are ever within a hundred dollars of each other, the decision flips and the Traeger is the better buy, because the warranty and the parts network come free at that point. That happens in the November sale window more often than at any other time of year. Check both live prices before you decide; the ranking on this page assumes the usual gap, not a sale.
Which one to buy, in three sentences
Buy the Z Grills if this is your first smoker, you want the most cooker for the money, and you are happy to walk outside to check on it. That is most people, and it is why it is our overall beginner pick as well as the winner here.
Buy the Traeger if you will use the app every cook, if a published warranty term is what lets you sleep, or if you want to buy pellets and parts in a store rather than online. Buy it discounted.
Buy neither if what you actually want is heavy charcoal smoke. No pellet grill produces it, and the honest alternatives are a drum smoker or a charcoal bullet. Our pellet vs charcoal comparison is the page for that argument.
What we are not telling you
We have not cooked side by side on these two grills, and nothing above is a taste test. This page is a reading of two makers’ published figures plus the beginner-fit reasoning we apply to everything on this site — here is exactly how we pick, including what we refuse to claim. We also do not publish reliability rates for either brand, because neither company publishes failure data and no honest source exists for it.
