I have cocktail tree with saijo, chocolate, honan, giant, fuyu, that fruit for me every year. The fuyu is a beast at producing as well as the honan. The saijo produces a few on its lone branch, but huge fruits. The giant fuyu its great producer as well. The chocolate produces the least (maybe 6-12 each year) but produces thousands of male flowers that pollinate the rest of the tree. The tree is near Spacex.
