I am not a big ice cream person but the flavors that I do, or did, like were Friendly's Snickers, Breyer's Peanut Butter Cup, and Gifford's Peanut Butter Iditarod, but the quality of ingredients isn't very high so they didn't hold up well after a couple of times.
The only flavor I enjoy now is Gifford's Peanut Butter Cup but I just found out they discontinued it so that only leaves TCCF as my dessert indulgence.
