I've played the T4 and S-950, but never used the pitch correction on either - never needed it. (Thankfully) The vocal processor itself on both the T4 and S-950 were very good - not to the extent the outboard processors are, but I would categorize them both as very good. Of course, if you cannot carry a tune in a five-gallon bucket, all bets are off with any vocal processor - both onboard and stand alone.
Good luck,
Gary
