I see nothing wrong with comping. Especially if I'm recording another band. My goal is always the best result possible. And I won't stamp my name on shit. It really depends on what your goal is. Most pros even comp. They'll play it "right" 3-5 times and the producer will pick the parts he likes best from each take and comp them. That being said, if you are talented enough to play your parts near perfect and feel that it's what you want after a single take, by all means keep doing what you are doing. But don't act like that's "right" or "standard" because it's really the opposite. If they had unlimited tape and tracks in the 60s and 70s you could bet your ass they'd comp the shit out of music. In fact, almost everything that makes a sound engineer's life easier becomes standard. Comping (and auto tune for that matter) is a tool to make great bands sound amazing. They shouldn't even be noticeable. If used as a crutch they will both make your music sound dull and make you a worse musician. You shouldn't have to punch every measure or so. That being said, I've seen many a band grow from playing takes 100s of times until it's right for the comping process.
