Okay, so I'm fine being AS. I don't know any other way so it's impossible to compare but it does have it's down side, even for a high functioning AS, such as myself.
For example, I suffer, and have suffered all my life, from endogenous, unipolar, major depression. That's not fun.
Also, I can be overloaded by certain social situations and I end up frazzled and cease to function - eg, this weekend my wife and I moved house. Lots of my wife's co-workers came to give us a hand. I knew none of them and they came into my house and were all very gregarious and friendly. They moved our stuff. The experience left me absolutely frazzled and I had to go away and stop myself from feeling like drowning. Fortunately, my wife knows all about this and was a star.
These aren't pleasant aspects of AS no matter how you look at it.
I'm lucky in that if there's an emergency then I can just get on and clearly deal with the situation but as in the latter situation there were too many people for me in my space and there was no real hierarchy nor emergency, so I didn't need to step in to get myself (or others) through the situation. This left me foundering in a NT situation that requires none of my abilities and no special reason to have to function in it.
Like I said, I was left frazzled and completely non-functioning for about 30 minutes to an hour until they all left.
AS isn't all bad but it isn't all good either.
