in a game like CSGo go ahead, use accel. You're alwasy aiming at standard, known points of interest and angles that never change ie doors, windows, edges of walls that you play consistently time and again.
Other than that, mouse accel is not something that should be promoted. I really don't think mentioning anybody gives any more justification, you're just name dropping. Regardless, I stand by what I said... accel is a niche topic and irrelevant to 99% of the playerbase.
