Depends on how you think this PH will be used. If he'll mostly be swapped for the pitcher, I'd take's Borton superior ability to get on base. If it's late innings when you're playing for that one run, Roth should be your man.
Another reason to like Roth is the extra speed. If your PH gets on base in a critical situation, you'll want the decent 73 speed Roth offers instead of the Molina-ish 50 speed offered by Borton.
