Arnold starred in cult movies like Terminator,Predator,Conan,Total Recall etc. Most of the Rock's movies I didn't even watched to the end,they are that boring.His biggest blockbuster is Fast and Furious and he isn't even a lead actor there.
Dwayne's championships titles in wrestling are just as real as Stallone's world titles in boxing and arm wrestling. Arnold is a 7xMr.Olympia,5xMr.Universe in BB and a Golden Globe winner in acting.The Rock doesn't even have abs.
