I really liked Cyrus because he seems so confident in who he is. Although, he did abandon Tyler in his hour of need. Sure he told a parent how Tyler was feeling, but still.. he could have helped him through it. I might have lost a bit of respect for him for that.
Definitely Cyrus. While I don't agree with all of his actions -- especially his effective abandonment and near bullying of Tyler -- its nice to see someone in the series that doesn't fear the jocks and will in fact stand up to them in their own way.
