DiGiorno is okay (I tried the pepperoni), but one big problem this company has is if you put the oven at the recommended temperature it always overbrowns the crust before the cheese browns (and is still room temperature). You have to really watch it and rotate it around the oven the brown the whole thing evenly. The sauce is okay but a little bit of a letdown taste-wise.
Freschetta has a good taste but the pepperoni does not cook fast enough compared to the rest of the pizza unless you bake it really brown (pepperoni tested). The factory, despite numerous complaints, has inaccurate machinery that tends to run the cheese and sauce over the edge of the pizza, making the baked product crust soggy and difficult to handle.
