In this battle, I gotta go with my gut and say that Red will win it. Ya, Gold beat 16 gyms while Red only beat 8, but Red had a much better rival pushing him to become better, fought and defeated a Team Rocket that actually seemed evil (Lavender Town and dead Marowak), and he has been on Mt. Silver, a mountain that is not habitable for even some of the toughest Pokemon can not survive on for the whole time between the two games (I think roughly two years but I can't remember).
oh okay.. but.. last year my brother showed me this pokemon black and white series with new protagonists, the trailer showed the new protagonists battling each other, is that and official series or..? oh and thanks for answering my first question ^^
