Shinn.

I find his personality to be far more interesting and a lot stronger than Kiras ( which isn't saying a lot seeing how Kira is the generic superpowered slash silent badass character. His voice pisses me off too! ). Asuran has been far too "meh" in GSD. indecisive, confused and really doesn't seem to have a cause. So yes, Shinn all the way for me.
