One of the issues here is that horses on a certain day will run to a certain standard based on a number of factors, including ground, left handed, right handed, flat track, rolling track, bigger fences , smaller fences, opposition, fast pace, no pace... and so ratings are for one moment in time. Only. And that's the problem with saying X was better than Y and would beat A and so on. If there was any way someone could invent a time machine, and change their ages and every other factor needed, and there was a match race of the two of them at their prime in conditions they both liked as much as sci-fi possible, at his prime and any other 2 miler at their prime, Kauto would win, 7 days a week and twice on a Sunday, because ultimately it's a contest, and he was an Ali. Not his fault that his record may be slurried in some eyes because he beat more Bugners than Fraziers.
