I grew up on the Swanson's brand as well, because back then it was the only brand.
Now there are so many different ones and those that are so much better.
The best ones I've tried are Marie Callendar's chcken pies and the turkey pies. I've had the pleasure of eating one prepared in her restaurant in Denver and it was wonderful.
I buy Shwan's now and they're pretty good too. The biggest complaint I have against these type of pies is that the bottom crust always seems to be gummy. So I just scoop it off and toss it into the disposer.
Oh gosh, I had forgotten about the Banquet brand, I think they were actually the original. Quite awful, actually.
