I have no real affinity towards Team Magma or Groudon, so their opposite numbers easily win out in this battle. It helps that I played Sapphire when growing up, so the nostalgia is there; but, even now, I have no real love for Groudon. It's kinda ugly looking, and - like Lugia - I always thought it was the wrong type (i.e. it should be a Fire-type). It's specious logic at best, but its those irrationalities that keep me coming back to Kyogre.
