If this is in-game, use whichever one you think is cooler. But as for which one is better in competetive, that'd be my buddy Meinshao. He is much faster, has access to a lot of good moves like Hi Jump Kick, Fake Out, and Stone Edge, has the ability to Baton Pass, run a Specs/Calm Mind set, and abuse U-turn (Which was a god-send) with Regenerator, which is arguably one of the best abilities in the game.
