John the 'Clueless',
Using your reasoning, it is also safe to say there is no greatest, boxer, golfer, tennis player, Formula 1 driver, baseballer, cricketer, basketballer...etc...etc.
If you don't want to have an opinion, then that's fine, but don't come here and tell us that because you can't work out who's hot and who's not, that no one else is allowed to form an opinion on who they believe to be the best galloper of all time.
