Pacino all day!

Personally I go with Pacino.  That guy is so freaking talented.  I mean, I he can do Shakespeare for cryuing out loud.  I would watch him do anything.

This is not to say that De Niro hasn't got chops, because we all know he does.  And I'd watch him 8 out of 10 times.  But Pacino... he has some kind of electricity that flows out of him.  He's lightning in a bottle!

Jim Carrey

Im sorry but DeNiro, he just has that mobster look and in all the movies a great mob mentality. I grew up on his movies and love em

Both actors are great in mafia roles.

Pacino...who else can pull off being a kingpin in two nationalities?

Pacino is more of a hood and deniro is your everyday mafioso im goin with de niro

Robert De Niro

Defentaly Robert De Niro

Pacino and De Niro both have had many great roles.

Pacino was amazing in "Scarface," "Scent of a woman," and "Donnie Brasco."

De Niro did great in "Goodfellas," "Meet the Parents," and "The Godfather Part 2"

All in all, I have to say that Pacino is the better actor.

There both amazing how could one say who's a better actor.

Both for me!:)
