Oddly enough, I would say Daniel.
I think Doyle has a lifetime of experience and great insticts coupled with an aggressive style BUT....
From what I have seen (limited, at best) I think Daniel's ability to read his opponents and his instincts of when to play certain "unconventional" hands IN ADDITION to the aggressive style, give him an edge.
Close call, though....I would LOVE to see them play some heads up!
