I'm definitely in "The End Justifies the Means" camp when it comes to doing things.
The only person who will know/care that you spent all day trying to nail your part in one go is you. The person who is listening to your mix at the end only cares about how that performance makes them feel, not how you did it. So if it takes 20 edits, or a bit of Melodyne to fix a bum note or timing or whatever, do it. The goal is to get the vision down for me, rather than the mechanics of it all.
Tell that to Glenn!
Anyways, all that may be true as long as you don't tell anyone. I'm finding the metal genre, in general, is less forgiving about corrections and "enhancements", which this essentially is - a way to record something that we can't actually play. Taken to its extreme, I could punch in two notes at a time for an hour and end up with a crazy fast guitar lead that I can't actually play, and was never actually played. It never happened. And that does seem to matter to some of us.
Anyways, not really disagreeing with you as much as just pointing out an exception in the metal crowd. Especially when you get into progressive this and that, the fans don't appreciate it much. If it came out that Animals As Leaders quantized, corrected and step recorded guitar tracks there would be a meltdown, ha ha!
