Another tomato that I've had good success with here in SWMO is Super Fantastic. Glad to see all the love for the Cherokee Purple, those ugly tomatoes are about my favorite too. A similar heirloom type is Black Prince so if you see any of those go ahead. I think it's always a good idea to have some variety. This year I went back to an old standby and planted some Better Boys, and two types that are new to me, Celebrity and Fourth of July. And of course Cherokee Purple.
