I have digitals BUT HATE THEM. But if your going to get one, make sure you get a good one. Airtronics, Futaba, KO, or JR. I like non-digital servos because they can be plenty fast enough without the penalty of draining a reciever pack after two or three heats. Between that and the sound, they get on my nerves. In onroad they may be a little more effcient for centering reasons etc. But JR servos are the best centering servos Ive heard, digital or not. This is just my opinion though.
