Breville Smart Oven Pro vs Cosori Air Fryer Toaster Oven Side-by-Side Comparison
Breville Smart Oven Pro vs Cosori Air Fryer Toaster Oven. Comparing them shows the aspects that define our best-to-buy toaster oven.

Specifications
Design
The Breville showed a lot of investment in its design from the exterior and interior to the accessories, especially compared to inexpensive units like the Black+Decker CTO6335S. For example, its carrying handles, interior safety hooks, convection system, internal lighting, feature toggles, and additional cooking functions. It does have some room for improvement, however.
The Cosori CO130-AO has a lot of design features, all of which are of high build quality. A few that stood out to us were the clear LED display, powerful convection system, large cooking space, high power output, and handy accessories like the rotisserie kit and air fryer basket. If we were trying to be nitpicky, we’d say the interior can be improved with a non-stick coating like the Breville BOV845BSS.
Usability Comparison
The Breville also shows investment in features of usability including the toggles and extra cooking functions in the user control as well as automatic mechanisms to increase ease of use. However, the actual delivery left a few things to be desired compared to the ones on our list of Best Large Toaster Ovens.
A well-designed automatic preheat phase, simple toggle options, and practical cooking functions gave the Cosori CO130-AO a good score. The cooking chamber as well as accessories could have better coatings to make them easier to clean, though. As an additional minor inconvenience, the oven doesn’t have a pause-resume mechanism upon opening and closing the oven door.
Performance Test
The strong power output of 1800 W didn’t seem to help with the Breville’s performance in our test dishes as much as other toaster ovens with the same output, including the Cosori CO130-AO. It performed the best in roasting a whole chicken but not to an outstanding degree.
This unit is advertised as having the Element iQ System™ which is a smart heating algorithm for improving heat distribution. However, our test results showed no significant increase in the cooking time or evenness of caramelization.
The Cosori CO130-AO, on average, performed great throughout all of our tests. It made full use of its high power output of 1800 W and its powerful convection system. To us, these were some of the main grounds for establishing the product’s value for the money. The included rotisserie kit and air fryer basket were also very helpful in our Whole Roasted Chicken and Baked French Fries tests, respectively.

Conclusion
The Breville Smart Oven Pro (BOV845BSS) and the Cosori Air Fryer Toaster Oven (CO130-AO) are both digital large convection toaster ovens. Thus, comparing them allows us to point out why the second contender is our pick for the best-to-buy toaster oven.
The two toaster ovens are equal in terms of interior features—both having an interior light, a convection system, and more than four heating elements. In addition, the Breville has a rare non-stick interior while the Cosori has a built-in rotisserie motor.
Exterior-wise, the Breville has side carrying handles while the Cosori has more air ventilation slats. Their premium build quality shows through their responsive control panel and well-insulated stainless steel casing, but the Cosori is just a bit better.
Both machines are easy to use, having well-designed cooking functions and an informative digital display. However, the extra toggle switches of the Breville failed to actually increase ease of use. The Cosori doesn’t have anything extra but it does have an automatic preheat phase that actually preheats to the exact input temperature.
In the end, the things that separates these two are their performance scores in toasting bread, baking pizza, roasting whole chicken, and baking fries. The Breville’s performance was inferior to the Cosori’s despite also having a convection system and the same power output. The key differences can be boiled down to the Breville not being able to maintain the temperature as constant and distribute the heat as evenly as the Cosori.
