personally i would have to say i prefer turn based rpg's. i tend to use more strategy in them as opposed to real time fighting where i would try to finish fights as fast as possible with as much brute strength as i can get. kingdom hearts for example i enjoyed very much but i didn't really care for the battle system cause i basically just hit the "attack" button as fast as i could whenever fighting someone. star ocean however is one of my favorite rpgs and i loved the real time battle in that one. so i guess it all depends on how it's done.
