Your palate may be used to the higher amount of sugar. I've found mangos often don't ripen well, probably due to being picked too early. Also there is a small like 1-3 day period where a mango will be it's best so you may have not really had a great mango. They taste even better if put in the fridge so it's cold.

No, dried mango have more sugar so it's better. I prefer dried fruits to normal fruits
