Not having flown the 757, I cannot comment on the relative merits, however I can say that I find the Airbus perfectly OK in gusty conditions. I agree with Bigpants, when light it can be a bit more sporting, but still perfectly fine. Also - 2 different aeroplanes - 2 different sets of wind limitations - I grant you, probably not that different, but different none the less.
Don't forget that places like FNC etc. have dramatically shifting winds as well as turbulence - it may be in limits for one a/c and completely out of limits and the wrong direction for the next, 2 mins later.
Cheers for now
