I wonder if the taste is dependent on location. Glen, Malika, Rosigold and Keitt are among my favorites.
I discontinued Carrie (too soft, average flavor, disease problems), and Lancetilla (bad flavor).
not crazy about Nam Doc Mai (too sweet and nothing else. Slight hint of sulfur, yikes). Wife's favorite Mango and many other people like them a lot, so I kept the tree. Very pretty, trouble free tree with nice, dense foliage.
Maha, tastes like a carrot, but many people like them. Problem free tree, so I kept it.
