It really strange as they say "one man's meat is another man's poison". I have stayed at Aonong a couple of times and would not go back but I would recommend Samui.
But then Mr Naz says that durian is one of his favorite fruits.......yuk. LOL
If you are very much in to rock climbing etc then Aonong would be good for you. You would be better to add some more detail about what your expectations of the holiday are and then people can get a better idea about what would suit you.
Not having a go at you Mr Naz by the way it just is always interesting to see the differences.
