Oh so many realy but for ones easily obtainable I would say Big Beef for the beefsteak and Sungold for the small one.... then a bit harder to find there is....... Cherokee Purple that I adore, plus Hillbilly, Paul Robeson, Souhern Night , Sugary,and Aunt Ruby's German Green, all are great in my opinion, I like a tom with a bit of a bite with sweetness too.
