Reading through the discussion of 3.5 vs. 4.0 convinces me (not that I needed it) if I ever went back to heavily playing it would be with GURPS. 
EDIT: Third edition GURPS (which was somehow contemporaneous with 2nd ed. AD&D.) I have not even looked at fourth edition, or much of any RPG since about the time WotC released third edition AD&D (which, based on my cursory exam at the time, bore a suspicious resemblance to third edition GURPS.) If the past trend holds, the release of AD&D 5.0 should mean GURPS is up to sixth edition, a possibility I do not wish to contemplate.
