Favorite here is Sleeping Lady. Two plants produced in excess of 100 medium tomatoes. They had a sweet, mellow taste that tasted great raw or when cooked. Everyone I shared with raved about the flavor and some asked if I would start seeds for them next year.
A second favorite was Hillbilly. Again a mild, sweet tomato taste.
These may not be the only two I grow next season but they are at the top of the list.
