The AF100 is a single-chip system. "3MOS" and "3CCD" are three-chip systems.
All MOS-based camcorders on the general market today use rolling shutters, and therefore all of them are subject to wobble, skew, etc. Some of them use faster read/reset times to minimize the impact of those effects. By my estimation, the AF100 is in the same company as the best of them. It can still be affected by those things, but there's not really anything on the market that will perform better in those categories.
