Can't beat a ripe peach. It tops a mango, IMHO, if barely. I've never had a tree ripe apricot or pluot, though.
I've always thought of mangoes as the peach of the tropics. But then again i was exposed to peaches at much earlier age than mangoes.
A tree ripened apricot is really an exquisite fruit. Right up there with the best of peaches in my opinion.
I've only had the pluots from the store, and they are ok, but not all that exciting. But then again most stuff in stores is not that exciting, so not surprising.
I still remember the plum in my backyard when i was a kid. Still have never tasted a plum that came close to that quality. All of these fruits really need tree ripening, ferts, and some TLC, to get to top notch premium taste.
