There isn't an answer to this question. Everything is up to chance like any other toyline. Most folks aren't getting problems, so I think that they're on par with other toylines. Heck, even Toybiz might not have been as bad as I always say - who knows - maybe I was just unlucky with all the breaks (and breaks I'm still getting years later). I've returned ONE MotUC figure so far and my only other problems were weak ankles, which I haven't seen in a good while. I'd say my personal assessment is that they have fixed the problems that bothered me and I haven't had many others. So we're good, yo.
