Kaine despite the clone shit is still fairly unique of a character.
It really only becomes a mess because of constant overuse of cloning for shit like that Spock mess.
Ben I never really liked as a character, he really seems like he existed to retread old ground that didn't need to be brought up, to the point even his name is a neon sign.
Gwen I could leave, but at least she has angst.
Miles needs a complete rewrite since Peter arguably fits more as a "black" character outside of the skin color than Miles ever does.
