APO : 16.9 X 10 x 12.4
BSO: 15.2 X 13.5 X 9.6
if the last unit is Hight , maybe the APO is better for bread baking ?
all other aspects being equal ?
1/4 sheet pan : 13 x 9.5
1/3d sheet pan: 15.5 x 10.5
so neither oven will fit a 1/3 sheet pan. approx.
more or less , the APO is $ 100 more.
best I could do on ' Opening Shots " of the two ovens .
when they ' start @ the drawing board '
wonder why no one had a 1/3d sheet pan
would have cost nothing really more to accommodate one.
