Well, yeah except I grow something different every year, just because I love to experiment. There's a thread specifically for Tomatoes on the Veggie forum, I think. (although some of those people are really convinced of the heirloom's superiority)
Another factor you have to allow for is growing tomatoes into the shorter days of winter. They simply have less sunny time in the days to make sugar so the tomatoes you get in December and January aren't quite as sweet as the ones that come along in April and May. I've seriously considered using lights in the dead of winter to give my tomatoes a couple of hours more light.
But they all taste a LOT better than any tomato you can buy in a store. I really haven't had too many without a really good flavor.
I've got blueberries coming along, and have grown quite a few herbs in my raised bed (that has been there for 7 years so it undoubtedly has nematodes in it). Peppers are susceptible to nematodes, but so far the herbs have been fine, and so have most of the salad greens, cabbage-y stuff and carrots. I had great carrots from there last spring!
