I voted for difference, but if I should explain it with my own words, I would say (as I use to when I explain it to others):
It is a condition that includes both handicaps, advantages and things that are none of these, but just oddities.
E.g. for my own part:
- a handicap could be inertia or awkwardness in smalltalk situations
- an advantage could be my ability to go deep into things and come to know a lot about them, or my more than average memory on certain areas
- a mere oddity could be my stimming like handflapping or making short hums that resound in my own ears.
So, that would be my description.

Agreed! This is exactly how I view AS. I voted the same way!
