No, my understanding is purple mangosteen is the only "real mangosteen" and the other garcinias can't compare. I have only tried purple mangosteen, though (and it is fantastic, btw). I'm growing seedlings of most the other garcinia types, including the two you mentioned, but I have no idea if they actually taste good. Some are supposed to be pretty good (achachairu, lucs mexican garcinia, and cherapu/button mangosteen I hear are good). They are all growing slowly but steadily for me. Only the purple mangosteen is stunted.
