That was a tough one....But I had to go with Deniro. Deniro has pretty much stayed the same over the years and has not changed into a whole different person with a raspy voice. But They are both great I just think DeNiro for the most part picks better films excep for Bullwinkel the Moose....what was he thinking!!!
Oh, C'mon - theyre both great - This is so not choosable - Sc*#w that, I'm voting for both
