In my experience, my in ground Cherimoya and Mango have been better tasting than the potted fruit. I’m sure if you’re really on top of your fertilization schedule, you probably wouldn’t notice a difference. I’m just guessing but I believe this is caused by the washing away of minerals/fertilizers from the soil of potted plants due to frequent watering. My Cherimoya in a pot still tasted good but if I recall correctly, it was 1-2% Brix lower than what I get compared to my in ground tree. The variety was HoneyHart.
Potted Mangos I’ve tried are Sweet Tart and Mallika. Mallika is inconsistent anyways but the potted Sweet Tart was still good, from memory.
It’s a toss up, I’d go with the fruit you want to eat more.
