Out of the two, who do you think is the best actor?

This is so hard for me as both are some of my all time favorites.

In the end I have to give the nod to Pacino. His amazing performances in Scent of a Woman, Dog Day Afternoon, And Justice For All, The Godfather, The Godfather 2, Serpico, Heat, Scarface, Sea of Love, Frankie and Johnny and others just does it for me.
