Build Quality
Overall Design Scoring

The Breville BOV450XL has a good capacity for a small oven. However, while it has a high wattage and quartz heating elements, it lacks a convection system, so the fancy heating elements don’t improve performance much.

Not being designed to accommodate a convection system was probably why it didn’t come with any useful additional accessories like an air fryer basket. And as a kicker, the interior has a non-stick coating but is black and contains no internal lights, unlike the Panasonic NB-G110P-K.

The Oster TSSTTVMNDG-SHP-2 has a simple and sturdy design, plus a convenient slide-out crumb tray. The large interior houses a togglable lightbulb and convection system. A consistent disadvantage that this oven has is its low wattage compared to something like the Ninja DT201.

Usability Comparison

User Control
Ease of Use
Overall Usability Scoring

The Breville BOV450XL is simple to use and to clean. Unfortunately, most of its unique features aren’t useful, including the toggles and cooking presets. Its smart heating algorithms as well as automatic preheat phase also didn’t add much to the test dishes we cooked. Cleaning it was an extremely easy task, though.

While the digital control panel of the Oster TSSTTVMNDG-SHP-2 is straightforward and easy to use, its buttons can be more responsive. In addition to that, having to press Cancel before changing functions can get annoying.

The convection fan isn’t all-applicable, but it’s not a problem. On the other hand, the oven’s design features, including its accessories, make cleaning an effortless exercise.

Overall Performance Scoring

The Breville BOV450XL produced great toast and adequate results when roasting a whole chicken and baking french fries. However, it left a lot to be desired when we tried a pizza. We suspect this was due to the inconsistent heating of the oven.

Moreover, the fact that the oven didn’t have a convection system didn’t help in this regard. A model of the same brand that improved on this was the medium-sized Breville BOV845BSSUSC.

The strongest performance aspect of the Oster TSSTTVMNDG-SHP-2 was the even coloring on our test dishes, thanks to its convection system. However, it didn’t meet the mark in baking frozen french fries.

This was probably due to the low power output combined with the large capacity, unlike the picks on our best toaster oven list. Moreover, having only two tray positions made it tricky to get the toast done right on both sides.

The Breville BOV450XL Mini Smart Toaster Oven and the Oster TSSTTVMNDG-SHP-2 6-Slice Digital Convection Toaster Oven are two units with interestingly similar overall scores, despite being on two different ends of the size spectrum—the former is small while the latter is large. The Breville is slightly more expensive though, which isn’t a good start for it in this competition.

A higher power draw enabled the Breville to pull ahead of the Oster in our Toast and Baked French Fries tests. However, the Oster was able to retaliate in baking pizza and roasting a whole chicken—we assumed because of its convection system. Curiously, the Oster had faster average cooking times even though it has a larger cooking chamber and lower power draw.

The Breville had a higher build quality shown in its more durable stainless steel casing and responsive buttons compared to the Oster’s. The fact that the Oster had a convection system gained it many advantages in terms of design but not enough to get a higher score.

Both toaster ovens were simple to use, but none were particularly convenient. Thanks to its non-stick interior coating, cleaning the Breville was more manageable. However, the Breville fell just short in terms of ease of use because its door can’t open partially to let food cool down inside.

Overall, it comes down to if you want a small and durable toaster oven like the Breville BOV450XL or an inexpensive and large unit like the Oster TSSTTVMNDG-SHP-2.
