It's Bobby all the way. Both are great actors and had great performances but Pacino has done some pretty bad movies. Gigli, 2 for the $, Insomnia. And he does play the same character in a lot of movies, the loud, angrey alwasy yelling (Any given Sunday, 2 for the $, Scent of a woman) And Denero has done very successful comedic performances. Denero's best movie- Deer Hunter. PAcino's-Godfather
