Speaking of glenn, that's another bullet proof, disease-resistant producer. Most of us tend to pan the glenn for its blandish flavor, but most of the mango newbies really enjoy it. We have 1/2 of a tree (roughly 1/2 is topworked to other cultivars), but my wife sells the heck out of the hundred or so fruits we get each year.
You should also look into Maha Chanok. My tree bears well every year and has no really issue with disease.
Ultimately, no tree is perfect. You have Production, Disease Resistance, and Flavor, but you can only pick 2. You also may have to do some experimentation based on your local set of circumstances.
