im not sure if you were comparing them according to manhood or parental status or wrestling skills or balls size?
Both had a steriod history, so balls are equal in this case.
wrestling skills, both are around the same thing
manhood, well we all know that cena is a smurf.
parental status, Batista is a grandfather lol.
mic skills I didnt mention as this is the only thing Cena is better at tbh.
As Great One mentioned, back in evolution; Batista was better by miles than Cena.
