Kevin Costner or denzel Washington?

I like Denzel a lot. Pretty solid actor, I have never seen him in a bad performance.

Kevin Costner is an actor that I like sometimes, Mr Brooks is a good example.
I find him very wooden in The Untouchables, I prefer to see him playing badass characters, like in Criminal or 3 Days to Kill (which is sort of a b movie, but i like his character Ethan and the father-daughter relationship, this is a feel good movie in my book).
