My first encounter a couple of years ago with APC was not good: frequent crashes...even Apache was crashing. Found out the version I had wasn't all that good, so we upgraded it, and APC has been running flawlessly since then. Completely "hands off" since the upgrade, in fact.
For the miniscule performance gain others have mentioned, I won't bother with Xcache. I do know that based on server load averages, APC cut our server load in half. Nothing to sneeze at!
