My IMO review and many things changed from year to year even some grown in my yard; I only went to two other places for a few of these. I will wait on some new varieties to grow.
Rosigold dropped from very good to below average taste and also poor disease resistance/fungus on fruit etc. in my location. Another disappointment is Sweet Tart in my yard for the second year in a row and varying ripening stages etc. I have found it (ST) to be worse than large Keitt in getting a consistent ripe fruit. It tends to hold more fungus on the fruit than Keitt also at my location and the splitting from the sun is worse than with Keitt in my location. Finally, the taste IMO has been extreme but extreme is not always desirable and unfortunately not for me yet. I do like salt and pepper on food but I do not like to eat only salt or only pepper and the same for the Sweet Tart mango so far. Hopefully, my opinion will change with next years crop as I found out with Madem Francis & Carrie developing a taste and the tree becoming more established and sweeter over the years.
Having mangos of varying taste profiles like tropical vs. lemony vs. lime vs. orange vs citrus vs. tart vs. sour etc. is great to create your own mango event eating your favorite flavor & then supplementing it with one of the other tasting profiles. This is why I consider many like philippean, for a lemony taste, okrung with eating skin to get a lime taste, orange sherbet for a orange taste, Florigon eating skin also for a citrus taste, as good as any other to eat with your favorite mango meal.
IMO Excellant: Carrie
IMO Very good: Keitt, Maha Chanok, Edward, Kent, Fruit Punch, Mallika (wife considers this her #1),
IMO Very good for flavors to supplement your main mango meal: philippean, duncan (for me this can also be a main meal), orange sherbet, okrung, sweet tart,
IMO Good: Madem Francis, Valencia Pride, Glen, Florigon, Haden, Young aka Tebow,
IMO Average Gift Mango: Pickering, Tommy Atkins
IMO Below Average: Rosigold
I did not try to try more mangos as no reason, no need IMO as long as you have this much variety, these choices are good to play with the various taste buds.
(Never eat mangos or mango skin if allergic to them.)
