The Martinez version of chavez wasn't definitely considerably better android more motivated. I think that version of Martinez was already starting to slide slightly but I'd still say 55-45 in Sergio favour. Prime Sergio I'd say 70 30
Prime Martinez boxes his ears off, maybe even stops him. Canelo struggled with the movement and boxing of Khan, how is he going to do against Martinez? Someone with great movement, skills but the size and power to match them.
