I've found it DEFINITELY faster and WAY MORE stable.
Those dreaded "run-time errors" that cause AC to crash are virtually gone. I still have trouble though when I do a consult letter attached to a long office note. When printing it "as one report," if it's too long the run-time error pops and the thing crashes. Aside from that, I don't have the problems that used to exist in V3. Plus there are so many better things about V4 that the pros outway the cons.
Maybe w/ V5 coming out soon and being CCHIT, we'll like that even better. I guess we'll see...
