Ive been using the Lm prestige for a couple of years now and recently changed to the pc 600. Im a real heavy hitter so i would think i needed less power. I would say in terms of being a "player's Racquet" the pc 600 stands higher. Im still trying to get used to the pc 600 as i miss hit occasionally even though my LM prestige was also a mid size. I only changed to the pc 600 after i heard marat safin uses it anyways racquet seems pretty good, the thing is i havent tried it with my ideal string combo so ill have to see how that turns out. Im also looking to add lead tape to the pc 600 because im have trouble generating a powerful 2hbh.
