Silas woods and Tikal are my 2 favorites, with Silas being the winner for smaller spaces.
Silas woods is insanely productive, and the fruits quality is top notch. I believe the silas woods to be a seedling of the makok. It has the dwarf and ultra-productive habit of the makok, but the fruits are slightly larger, with white flesh, and a less intense / smoother flavor (honey vs panela). The only drawback is that the wood tends to be brittle. It's very common to find broken branches due to the weight of the crop and / or raccoons feasting on immature fruits.
Tikal is extremely productive, fruits twice per year (smaller crop is in the summer), and the fruit is extremely delicious. Pine Island's variety viewer gives it low rankings in production and flavor, but that betrays my experience with the tikal -- which is completely the opposite.
