I think that, for fruit lovers, it's very difficult to do a top5 list
The fruits I eat most are apples and bananas, because they are easy to eat and to find in the market, but I really love a lot of fruits, and a good feijoa could be first on my list: but I didnt included it! I just forgot, but they are super tasty here... and for sure: a Mango could be first too! and I didnt included it! or any good Eugenia or a strawberry guava too, chirimoya!!, etc.
And I would also produce them comercially: feijoa, strawberry guava, etc., because they are super good fruits
I tend to believe that the last rare fruit I tried it's my favourite fruit if it was very good, for instance, jaboticaba
chirimoya, mango, jaboticaba, lychee, jackfruit, uvaia, etc., are way too good not to be in a top 5, but you are missing a lot of good fruits too
