Best Pitcher In MLB Today?

I know most people will say Roy Halladay (I agree) but I feel as if it is not clear. There are so many pitchers in the league who can challenge him. I have no problem with people who say Felix, Timmy, JJohnson etc are on the same level or better. I feel so privileged to be able to watch the MLB. There are so many good pitchers I can't believe it.
