Table Ace is a small ( 2-3 lb) green semi- vining hybrid hybrid. I t is sold by Johnny's who considers it a good choice for commercial growers. Table king is a bush 3 lb open pollinated green Acorn. I have not grown either of them, but have good results with the bush Table Queen. All three are rated at the Cornell site.

I believe I have grown all 3 at one time or another. My favorite is the bush Table Queen. The bush habit is much easier to handle and IME you get 4 or 5 per plant. They are about the size for 2 people, split and cook. They are delcious.
