I also have a 22" TravelPro rollaboard (a non-suiter version) and it fits in every AS bin perfectly, though it's a tight squeeze on the -400's. As long as you don't stuff it overflowing, it's the perfect mix of ample space inside and overhead bin compactness.
Do you regularly travel with a suit? I wouldn't opt for the suiter version unless you need it almost every time. If you only occasionally need a suit, you could just make do with a garment bag hung up in the closet and save the space in your carryon.
My TravelPro goes with me on every trip regardless of length or destination. You picked the right brand.
