Of those you mentioned, I've tasted Fruit Punch, Pineapple pleasure, Mahachanok, and Nam Doc Mai
Below is based on my unrefined taste:
Fruit Punch is a nice size and pretty fruit.
I think I understand why they call it Fruit Punch.
To me, it has this sort of mild "chemically" taste (from the terpenes I suppose) that reminds me of Hawaiian Punch.
Not in a bad way though.
I enjoy the flavor but wouldn't want a whole tree (multigraft branch status)
Pineapple Pleasure is nice.
The color of the interior of the fruit does look like pineapple sometimes.
Tastes similar enough where I wasn't scratching my head at the name.
The texture was the drawback to me, though this might be a phenomenon of big mangos.
The interior was beginning to get soft when the outside was ready.
I like it enough to be happy have it in a crowded mango season but wouldn't care for the tree (get from a friend or buy status)
Mahachanok is wonderful.
In every way, I can imagine.
It has that wonderful sap smell that Black/Buxton Spice (the classic from Guyana), Coc/Cac, ZINC (at its descendants) have.
Also described by Cookie as a coke a cola smell.
I'd plant a few trees if I could.
Nam Doc Mai is good, not great but just good.
Its pretty simple, not crazy flavors. I don't even think it taste like a mango sometimes.
It's just too plain and sweet for me at fully ripe for me to enjoy a lot.
When I say plain I don't mean plain like a "normal" Florida classic flavor, I literally mean plain like sugar, orange food coloring, and pectin
I find it also has a musky flavor when it's fully ripe.
I enjoy it best at a semi-ripe stage when it has some acidity to round out the flavor.
It still tastes good and would be happy to have it in a limited mango season.
I'm in the process of muligrafting mine.
