In terms of sheer magnitude, an Eastgate win would obv be huge since no one has even come close to repeating in the Moneymaker era. But Ivey winning would make him he biggest star poker has ever had, which would be better for the game in the long-run. Think of the effects Doyle Brunson/Stu Ungar have had on the continued popularity of the game, but on crack.
this along my lines of thinking. While Eastgate winning would be huge an Ivey win would cement him as the greatest living player imo
