I've had Red Barron pizzas. I can't remember the specific varieties, but I know I've had more than one cheese-only topping pizza in the last year or so. I didn't think it was the best thing ever, but I had no complaints, particularly given the price. Indeed, I have a sense that it was a welcome buy at one point--really cheap at a point where the grocery budget was practically used up for the month...
That said, the only pizza I've had in recent history has been frozen. And my budget hasn't permitted buying better varieties in some time--the mass market brands are the best I've had in quite some time. Also, while I had Red Barron in the last year, it's been a number of months. So it's entirely possible that the recipe changed between my last pizza, and Dave's.
It's been a long time since I had Freschetta, but I liked the brand many years ago. BUT I haven't been as happy recently, although it's been more "disappointing" and "not as good as I recall" than "this stuff is so terrible and I won't finish it!" (I can't recall what topping varieties, but it would have been something meat free.)
Although, for me, it's irrelevant how good or bad these brands are. I no longer eat dairy, and assuming I stay away from dairy for the duration, it's not terribly likely I'll have any conventional frozen pizza again.
