someone correct me if I'm wrong but from what I've gathered:
E-4 sugar loaf: pineapple/coconut flavor, green mango, mid season, slow growing spreading habit, not sure about disease resistance yet
orange essence: citrus, yellow mango, mid season, vigorous upright habit, leaves get a lot of mold during the winter but no other problems
honey kiss: traditional, red mango, slow growing spreading habit, good disease resistance
