Advantage of window seats are a bit of extra storage, and the windows obviously but I prefer to seat on E and F seats (when in couple) and have direct aisle access.

I personally prefer the first cabin, just to be as far as possible from screaming babies at the beginning of economy cabin. (But I'm quite partial to baby crying for 8 hours...).
