It's a difficult one to answer - how do you compare 2 star horses who are both brilliant but very different? One was a natural mile and a half champion who did well to win the Guineas on the way, one has the rest of this season to show how good he is, but looks like a superstar speed horse, with a mile around the limit of his top gear.
For their 2000 Guineas performances, Frankel was visually more impressive, but perhaps beat less than Seathestars did (time will tell). Frankel's time was worse, but apparently there was a strong headwind. Frankel looks the better 2000 guineas winner, though whether that becomes consensus opinion will depend on how he performs for the rest of this season.
