I like almost all fruits, but of the ones I've tried I'd probably say papaya is one of my least favorites, and also apricots. Blackberries don't do it for me either, although I won't avoid them...just not amongst my top 10.
My favorites are kiwi, berries (especially raspberries), oranges, melons, and pineapple. I used to love bananas but find them too sweet to eat most of the time so I just have one every now and then. I do eat a lot of apples, too.
