Better than Ronnie, better than Dorian and better than Arnold..."small arms" and all
8x Mr. O.....No losses as Mr. O and went out on top and still healthy today. Great spokesman for bodybuilding and wonderful family man.
If you count being the best by flawless victories, Dorian wins cause in all his Olympia wins he did not lose a single round, so his victories, once already at the top, were unrivaled by any Olympian winner.
If you count who has the most Olympia Sandow, Haney is the best but tied with Ronnie, so not exactly the best but the position would be shared.
Now if you count the best being by how may Olympia's could have been won, well Arnold by a long shot, any expert in the world agrees that Arnold at the very least would have won from 1970 to 1980 and that would make 11 and possibly even 1981, 82, 83 so would make 14. Haney would not have made 9 no matter what cause Dorian almost stopped him in 1991 by winning the muscularity round and the the entire prejudging. also Dorian improved by leaps in 1992. Now Dorian also would not have been able to win anymore either as he had to many tears, and Coleman lost at the end as well. So Arnold clearly wins as the potential Sandows.
So clearly if you claim Haney is the best you have to include Ronnie or if there is another reason for thinking so it is only an opinion otherwise.
Truth is Dorian was the best of all time cause he had the least losses with the most dominant and flawless wins, not to mention in an era where 80% of the entire bodybuilding community agrees was the most dominant and strongest era.
