Who's the better poker player?

Is it the No Limit Texas Hold 'Em specialist that wrote a book called "The Mathematics of Poker" and now takes down tournament after tournament, even winning two World Series of Poker bracelets (read: William "Bill" Chen)? Or is the old school guy who's been around seemingly forever and has the overall poker knowledge to take down the 2006 WSOP H.O.R.S.E. event (read: David "Chip" Reese)?

With the fields larger than ever and amateur Hold 'Em players becoming more skilled than ever, winning a single WSOP bracelet is highly improbable for even the best of players. Consider that the two players often regarded as the current best in the world (Daniel Negreanu and Phil Ivey) both failed to win a bracelet in this year's World Series. So to win two Hold 'Em bracelets in a single year seems nearly impossible -- granting Bill Chen's feat legendary status among poker pundits. However, to win the H.O.R.S.E. event, one has to be a master not only of Texas Hold 'Em, but also of the less widely-played games of Omaha Hi/Lo, 7-Stud, Razz, and 7-Stud Hi/Lo.

So which is a stronger testament of a player's skills? Is it being an undeniable expert a single game, or being extremely solid at a variety of games? I have my opinion, but I am curious to see what others have to say about the topic. And please, I'm looking for general answers, not asking who's better between Bill Chen and Chip Reese.
