The PRS trem does go out of tune with heavy bends, especially the G string but a quick dip of he bar brings it back into line - for most I'd say a Floyd is overkill. But it does feel different underhand and there's no doubt it stays in tune better if doing Vai/Satch antics. I think the PS trem with locking saddles probably works as good as a Floyd (wish those saddles were available on the core range.. Would be ordering another PRS if it did!).
