I will play, this needs to be in tiers for me.
Tier 1 : Durian
Tier 2: Mangosteen, Rambutan, duku langsat, Mango, Achacha, abiu
Tier 3: Sapodilla, sugar apples, citrus, rollinia, plus many others
Wow, Durian is in your top tier. I am not even thinking of tasting it ( I am obviously novice on this fruit.)
I haven't heard some of your fruits such as duku langsat, Achacha, abiu, rollinia.
Durian is considered the undisputed KING of fruits in SE asia which is the epicentre of diversity in tropical fruits, you wont find many in the US agreeing with this as it doesnt fruit on mainland US, once you get into true tropical regions durian is KING, some of the other ones i mentioned are also excellent again truly tropical so you wont find much discussion around these as this is a cont US based forum.
