I was told that when I was looking at one initially, and I found that not to be true. My 6 jaw clamps just as tight as a 3 jaw (and there isn't really a good reason why it wouldn't, its still a scroll chuck, just with the pressure moved to 6 jaws instead of 3, same force, just more spread out), but I find it damages surfaces less than a 3 jaw, and holds them just as securely.
I realize it isn't 'more accurate', but it is no less accurate either. In my experience, it is just as good as a 3 jaw at everything a 3 jaw chuck does, PLUS it is more gentle on the workpiece, AND does a better job holding parts 'squarely' that need to index off the face of the jaws. Before I bought it, I read a number of threads about them with the issues surrounding them, but never found any of those to be a problem in practice.
In the 3-4 years since I bought my chinese 6 jaw, BOTH of my 3 jaw chucks have sat on the floor and haven't moved since.
