If you want maximum capacity and a stainless-steel build for feeding a crowd, choose AboveMoon Stainless Steel 8Qt; if you need a slimmer, lighter air fryer with simple presets for everyday family meals, choose Martha Stewart 6-Quart.
• AboveMoon's biggest strength: an 8-quart square basket that fits 4–6 people, a whole chicken, or up to 2 lbs of fries, plus a heat-resistant viewing window so you can watch food without opening the drawer.
• AboveMoon's biggest trade-off: it weighs 9.5 pounds and takes up more counter room at roughly 11.5"D x 12"W x 12.5"H, so it's a commitment in a small kitchen.
• Martha Stewart's biggest strength: a slim 6-quart body (about 17"D x 10.7"W x 12.8"H) with six one-touch modes and a higher 1750W output, so it's genuinely easy to live with day to day.
• Pick AboveMoon if you cook for 4–6 people, want stainless steel and dishwasher-safe parts, and value being able to peek at your food mid-cook.
• Pick Martha Stewart if you want a compact, preset-driven air fryer for 2–4 people and prefer a straightforward dial-and-touch setup.
The AboveMoon is built around one idea: volume. An 8-quart square pot is a real design choice, not just a number — the brand states the square shape holds about 25% more food than a round basket of similar footprint. In practice that means a whole chicken fits, two pounds of fries fit, and you can run a single batch for a family dinner instead of cooking in relays. If you've ever stood over a small air fryer cooking wings in three rounds while everyone else eats, that's the problem this unit is aimed at.
The cooking side is straightforward but capable. It runs at 1350W on standard 120V power, with an adjustable range that reaches 400°F and holds temperature within about ±5°F, using 360° turbo air circulation for browning. What I find genuinely useful is the dual monitoring setup — a heat-resistant window plus interior illumination — because it lets you check progress without pulling the basket and dumping heat. The backlit touchscreen handles mode and time changes, and the 200-minute timer is unusually long, which matters if you ever dehydrate.
Then there's the convenience layer: a memory function that resumes cooking after a power interruption, a 30-second auto heat-dissipation cycle after cooking, auto shut-off, and a basket pause. Removable parts are dishwasher-safe, which is the detail that tips this one for a lot of households. The stainless steel finish and metal inner pot also mean you're not worrying about scratching a coating. Who should skip it? Anyone cooking for one or two, or anyone with a tight counter. At 9.5 pounds with a 12-inch-wide footprint, it's a piece of equipment, not a gadget you tuck away.
The Martha Stewart 6-Quart is the opposite philosophy: do fewer things, but make the daily routine frictionless. The 6-quart basket is still described as fitting up to 3 lbs of fries, a whole chicken, or a family-sized batch of wings — so it's not small, just narrower. The slim body and Sky Blue finish make it the kind of appliance you don't mind leaving out, which in a real kitchen often matters more than raw capacity.
Operation is the selling point. There are six modes — Air Fry, Bake, Roast, Broil, Dehydrate, and Reheat — selected through an LED touch display with a dial for mode, temperature, and time. It's the layout I'd hand to someone who doesn't want to learn a menu system. Two features stand out for everyday cooking: an integrated shake reminder that tells you when to toss the food for even browning, and a smart sleep mode that kicks in after five minutes of inactivity to save energy before powering down later.
On power, it's rated at 1750W with rapid air circulation and a 400°F max, so it heats aggressively for its size. The trade-offs are worth being honest about. The basket uses a nonstick coating and is hand-wash recommended, so you're washing by hand and you'll want to treat the surface gently. There's no viewing window, so you check doneness by pulling the basket. And 6 quarts, while generous, is a step below the AboveMoon — fine for 2–4 people, tighter if you regularly feed five or six. The ceramic and stainless steel exterior is a nice middle ground: sturdy, but not the all-metal build of the AboveMoon.
Side-by-Side: Which Should You Choose?
• Best for large families (4–6 people) → AboveMoon Stainless Steel 8Qt. The 8-quart square pot and whole-chicken capacity are the deciding factor.
• Best for batch cooking and meal prep → AboveMoon. The 200-minute timer and bigger basket handle long, multi-portion sessions better.
• Best for set-and-forget simplicity → Martha Stewart. Six presets, a shake reminder, and a dial-driven interface leave almost nothing to figure out.
• Best for monitoring food mid-cook → AboveMoon. The viewing window plus interior light means no heat loss from opening the drawer.
• Best for easy cleanup → AboveMoon. Removable parts are dishwasher-safe; the Martha Stewart basket is hand-wash recommended.
• Best for a metal, coating-free cooking surface → AboveMoon. Stainless steel inner pot versus a nonstick-coated basket on the Martha Stewart.
• Best for faster heating in a compact body → Martha Stewart. 1750W versus 1350W, concentrated into a smaller cavity.
• Best for energy-conscious everyday use → Martha Stewart. The smart sleep mode shuts things down when you walk away.
If I were buying for a household of four or more, I'd take the AboveMoon Stainless Steel 8Qt. The 8-quart square basket, dishwasher-safe removable parts, stainless steel interior, and that viewing window solve the problems that actually annoy me about air frying — cooking in batches, guessing at doneness, and hand-washing a coated basket. In my opinion it's the better long-term buy for anyone who cooks real meals rather than single portions.
The Martha Stewart 6-Quart wins on a different axis: it's the one I'd recommend for a couple or a small family who wants a compact, preset-driven machine that heats hard and stays out of the way. Check the current price on Amazon for both before you commit, since that's the one variable that can flip this decision either way.
FAQ
The Martha Stewart 6-Quart, based on the specs. It's noticeably slimmer than the AboveMoon and uses a dial-plus-touch interface with six presets, so it takes less counter space and less learning. If you can spare the room and want more capacity, the AboveMoon's 8-quart square pot is the trade-off.
Look at capacity and timer length. The AboveMoon's 8-quart square pot, whole-chicken capacity, and 200-minute timer make it the better batch-cooking machine of these two. The Martha Stewart's 6 quarts still fit up to 3 lbs of fries, but it's better suited to smaller, more frequent batches.
That's a different brand, and these two sheets don't include Ninja models, so I can't compare them fairly here. If Ninja is on your shortlist, judge it on the same criteria I used above: basket capacity, wattage, whether the basket is dishwasher-safe, and how simple the controls are.
