May I start a new topic? c: I think most of the generic topics have been posed already, so how about a debate? :D
You can take the word 'better' in any sense of the word, be it competitively or just which is more awesome, so it should be a tough match-up! Personally I prefer Bronzong in almost every way. I think it's better in battle due to its more defensive nature and more interesting abilities/moves, and I think it looks a heck of a lot better. I find Bronzong's uniqueness very appealing and I just find Metagross too... angry? I dunno, but the way its eyes connect to the cross on its face makes it look so unapproachable and it's not something I'd ever want to train as a result. I admit that it sure can pack one hell of a punch, but I think Bronzong is just much more pleasurable to have as a partner and on a team. Especially with its abysmal speed and access to Gyro Ball/Trick Room + Toxic, Bronzong is one hell of an opponent. :3
