I'm one of the few that uses differential on almost everything. I can fly without it, but where I really notice it is if I have to make a correction that requires using more aileron. If there is adverse roll because the airplane needs some differential, it will throw the heading off while your making a correction, compounding the error you already made. A big key to going fast and winning is minimizing mistakes, and when you do make them, keeping the time to correct them to a minimum.
