The Ninja SP101 and the Ninja Flip SP151 are both 1800-watt countertop ovens that flip up and away for storage. They share a similar design, so the differences come down to the controls, the rack, the depth and the pan sizes.

This comparison covers the two on controls, cooking room, counter space and what comes in the box. It helps you pick the one that fits your counter and the way you cook.

Ninja SP101 vs SP151: which one has the better controls?

The SP101 uses knobs, and the SP151 uses a button panel with an auto cook menu. Knobs suit people who like to change a setting with one turn, while buttons suit people who prefer preset meals.

The SP151's auto cook menu gives a shortcut for common foods, so you pick the food and the oven sets the rest. The SP101 relies on your own settings, plus a toast darkness selector for bread and bagels.

Is the Ninja SP101 or SP151 easier to use?

Neither one is easier for everyone. If you change the temperature often during a cook, a knob is quicker to adjust, and if you cook the same few meals each week, the auto menu saves you from setting each one by hand.

How much food fits in each oven?

The SP101 is the one to pick if the pan size matters most. Ninja says it fits a 13-inch pizza, up to 9 slices of toast and 6 chicken breasts.

Ninja says the SP151 bakes a 12-inch pizza and toasts up to 6 slices. It air fries or roasts up to 4 pounds of food and fits 6 chicken breasts, so it works well for a family dinner in one batch.

Which one takes less counter space?

Both ovens say they take about half the counter space when flipped up and away. Ninja's figure is 50 percent for both, so the real saving depends on where the oven stands.

The SP101 is about 2.7 inches deeper than the SP151, at 19.7 inches against 17.0 inches. That difference can matter on a shallow counter, so measure before you order.

When the oven is flipped up, keep the cord loose so the plug and outlet aren't under strain.

Flipping up the oven also changes your daily routine, since you lift it to clean behind it or to store it. A heavy unit that you lift every day gets tiring, so think about how often you'll move it.

Which Ninja is better for reheating leftovers?

Both ovens can reheat leftovers. The SP101 includes keep warm among its eight functions, and the SP151 includes reheat among its settings.

For leftover pizza, the air fry setting on either oven can bring back a crisp crust in a few minutes. Check the slice partway through, since a thick slice may need a little more time.

Use the wire rack, not the pan, so air reaches the bottom of the slice.

How do the heating and temperature ranges differ?

The SP151 runs from 85 to 450 F, and Ninja says its six infrared elements heat the food evenly. The SP101 uses Ninja's Digital Crisp Control, which Ninja describes as precise control of heat, airflow and temperature.

Ninja says the SP101 preheats in 60 seconds. Check the owner's manual for the full temperature range before you cook a dish that needs a low, slow setting.

Ninja SP101 vs SP151 for bread, toast and bagels

Both ovens toast and make bagels, so the question is how each one handles bread. The SP101 has a toast darkness selector, which lets you set how dark each slice gets without guessing.

The SP151 has bagel and toast settings on its button panel, and its auto cook menu handles a batch of toast without a manual setting each time. For a quick two-slice breakfast, a toaster can still be the faster tool, while either Ninja fits a full batch of toast in one go.

What comes in the box?

The SP101 includes an air fry basket, a baking pan, a chrome-plated wire rack, a crumb tray and a cookbook. The SP151 includes an air fry basket, a crumb tray, a sheet pan and a wire rack.

Both include a crumb tray, so pull it out after any cook that drips or throws off crumbs. Wipe the racks and pans after each use, since grease left on them can smoke during the next cook.

Which one suits a small household or a family?

Ninja describes the SP151 as feeding up to 4 people in as little as 20 minutes, which suits a small family or a couple who cook for guests. Its auto cook menu helps with quick weeknight meals.

The SP101 suits a household that bakes a full 13-inch pizza or uses a sheet pan for crisp vegetables. Both ovens are sized for a kitchen with limited counter space, so the choice comes down to the meals you cook most.

What about cleaning and upkeep?

Both ovens are easy to clean in the same way. Pull out the crumb tray, wash the racks and pans after they cool, and wipe the inside with a damp cloth.

Ninja says the SP101 has an easily accessible back panel for deep cleaning. That helps if you want to clean behind the heating area, though you should check the manual before you open any panel.

What should you plan for on the first day?

Set the oven on a flat surface with clear space on every side, and check the manual for the clearance it asks for. Plan the flip-up path before you unpack, since you need a clear route to lift the top.

Run a short test cook with a simple food, such as frozen fries or toast, so you learn the timing. Pull out the crumb tray during the test to see what falls off, and wipe the racks once they cool.

Read the toast shade and time settings once before the first cook, so the first slice isn't a guess.

How do the scores compare?

Our score weighs specs, features and buyer feedback against what you're shopping for.

The SP101 scores 8.8 for its knob controls and its pan that fits a 13-inch pizza. The SP151 scores 8.6 for its button panel, its adjustable rack and its wider temperature range.

Which one fits a shallow spot or a corner?

The SP151 is the better fit for a shallow spot, since it's about 2.7 inches shallower than the SP101. It's about 0.8 inch wider, though, so measure both numbers before you decide.

Either oven needs side room for airflow and for the flip, so a corner spot needs more clearance than a flat counter. Measure the full path, including the flip and any side swing, before you commit.

How do the two ovens fit a busy weeknight?

For a weeknight meal for two, the SP151's auto cook menu gets a preset dish on the table with the fewest steps. The SP101 suits a cook who likes to adjust the heat partway through, since the knob makes a quick change easy.

Either oven covers a weeknight tray of vegetables or a small pizza. Pick the one whose controls you'd rather use on a tired evening.

Whichever you choose, wipe the crumb tray after each cook so crumbs don't build up between weeknight meals.

Which Ninja flip-up oven should you buy?

Pick the SP101 if you like knobs, need a pan that fits a 13-inch pizza and have the depth for it. Pick the SP151 if you want buttons, an auto cook menu and an adjustable rack.
