I prefer more active battle systems. Turn-based needs strategy to be pulled off effectively, otherwise it's grossly unstimulating - battling just for the hell of it. If I wanted that, I'd just go play a wrestling game. Many turn-based games lack this element.
Active battle systems bring an element of skill into the gameplay. It can be quite difficult to balance latency (where applicable) with staying alive - or resources such as spells, skills, items, ammo, whatever in other cases.
