The benefit is small, but evident. I prefer compensated Glocks, but it's not a deal breaker by any means.
I found that adding weight to the muzzle was a much more effective way to reduce muzzle flip. I have a thread-on compensator on my G24 and a flashlight on my G23c, and the addition of those parts made a HUGE difference in felt recoil and muzzle rise. Possibly more noticable with .40s&w though being that it's known for being snappy.
