Agreed with Avan about the pilots, but as Aker said, its not about the pilots.
I'd say Basic Gundams vs Basic Knightmares, it belongs to the Gundams
But when it comes to the advance Knightmares, I've got to give it to the Knightmares. They do crazy things that I haven't seen in Gundam, though I have a limited Gundam experience.
