Build Quality
Overall Design Scoring

The Oster TSSTTVFDDG is one of the largest capacity ovens we have tested. However, it lacks premium features often seen in the same price range including having more than 3 rack levels or a non-stick interior,e.g., the Breville BOV845BSS. Features worth mentioning are good ventilation on all sides and the upper heating element.

The Ninja DT201 shows a high build quality in all of its design features from the exterior and interior to the included accessories. What stood out to us the most was the powerful convection system and the number of heating elements. We couldn’t confirm the accuracy of the Ninja’s claim that it had ‘up to ten times the convection power’ of a traditional full-size convection oven, though.

Overall Usability Scoring

While the Oster TSSTTVFDDG is straightforward to use, it lacks premium features expected of similar-priced ovens including light and convection toggles as well as safety mechanisms.

The straightforward control panel on the Ninja DT201 allowed for easy adjusting and readjusting of the cooking settings. Moreover, the informative display combined with distinguished buttons removed all of the guesswork when it came to operating the oven.

The oven’s practical cooking functions shined all the more in combination with the 2-level even cooking feature. The oven’s interior could be improved with a coating for easier cleaning, though.

Overall Performance Scoring

For roasting (which doesn’t require high heat) the Oster TSSTTVFDDG did well. However, it took time to reach higher temperatures. Additionally, it didn’t perform well with toast, pizza, and especially french fries that require higher temperatures for longer.

The Ninja DT201 performed differently on each of our tests but even at its worst, it still gave good results. We were most impressed with the oven’s ability to quickly reach and maintain its temperature despite the large cooking chamber. This could be attributed to the oven’s high power output, powerful convection system, and a total of 5 heating elements.

With these factors, you don’t even need to turn food during cooking, especially if you incorporate the air fryer basket. Interestingly, this was one of the few units where we felt increasing the food amounts would lead to even better results.

The Oster French Door (TSSTTVFDDG) and the Ninja Foodi XL Pro (DT201) are two of the largest toaster ovens on our roster. At first glance, the Oster is slightly larger and also more expensive than the Ninja. However, our tests showed that the former was inferior to the latter in every aspect of evaluation.

Exterior-wise, the Oster has ventilation slats on all sides that we like. Its glass french door with cool-touch door handles also stood out well.

Unfortunately, the main thing pulling the Oster behind is its build quality. Its buttons require a lot of force to register and the french door can slam shut if your hands slip. On the other hand, the Ninja’s door hinge is firm and its buttons are responsive and intuitive to use.

The Oster also has no extra features to help with conveniences like toggle switches, other information besides timer and input temperature, or a slide-out crumb tray—which the Ninja does. Performance-wise, the Oster wasn’t equipped with a high power output and powerful convection system to deliver the utmost cooking capabilities like the Ninja.
