I have a Hasya that I bought in the summer. Here are acouple of pics of Makok and Molix in Santa Ana. The Molix is really productive the fruits are large.
Molix

Hmm that's a tough one. For pot culture the makok is a winner. It's very productive and can be kept at 6 feet tall indefinitely in a 15 gallon pot with pruning (according to fshs). If you don't thin out the fruit, the makok fruits are small and extremely sweet. If you thin out the fruit, they are less sweet (which for me is better), but they have many seeds (sometimes 8 seeds per fruit). Personally, I'd probably choose the makok just because it's better suited for pot culture.

If you can get one, the silas woods is reported to be a dwarf tree that produces delicious tasting fruit.
