The Breville is so vastly superior in every way - function, capacity, ease of use, and ease of cleaning. I cannot recommend it highly enough.
The timer on the Breville turns the oven off at the end of any kind of cycle as you would expect - toast, bagel, bake, broil, pizza, etc.This is hugely wonderful compared to the Cuisinart unit which only turns itself off after toasting - you have to remember to turn it off when in any other mode. (The Cuisinart's timer is 'dumb' - just a beeper.) Also, each Breville cycle has smart default settings, and can remember your own settings for temperature and time, or slices (toast) and darkness, etc.
The BOV800XL accomodates a 13" pizza pan (included). We made two pizzas tonight to test the oven, one fresh (deli) the other frozen. I dialed the 'pizza' setting, dropped the default 450 temperature to 425, accepted convection mode, and accepted the default 12" size for the fresh pizza and pressed the on button. Once preheated, the oven beeped for the pizza to be inserted. At the end of the timed cycle, the oven turned off and beeped again: perfect pizza!
I then did a 9" frozen Amy's pizza. Similar procedure as above, but dialed the size knob down to 9" and pressed the 'frozen food' button. Again, perfect at the end of the cycle.
Toast setting works great - up to 6 pieces of toast, as does the bagel setting, which toasts the top at a higher temp then the bottom to make the top crispy and the bottom warm but still soft. Frozen waffles come out great - crunchy outside and moist inside, instead of all dried out. Breville BOV800XL
For baking, a 13" x 9" baking pan easily fits inside as does, of course, the larger pan that comes with the unit, loaf pans and small muffin pans.
The glass door conveniently labels the three rack positions for broil, toast/cookie/bagel/pizza, and bake/roast/reheat/warm.
The crystalline-looking heating elements (three on top, two on the bottom) seem to heat faster, and more evenly, than the metallic elements in other counter-top ovens. Depending on the mode/cycle, the oven enables or disables certain elements, and changes the wattage of others.
