Whats interesting is Kasparov himself said , here in Lisbon, that the only way to compare champions from different eras was by how much they dominated their peers and he said by this measure Fischer was the best ever. Kasparov said this himself.
Well, Sonas both agrees and disagrees... he basically fudges, saying, "I think it's pretty clear that for about a year, Bobby Fischer dominated his contemporaries to an extent never seen before or since." So Fischer is #1? Not for Sonas, he actually drops Fischer down to (check your pacemaker Reb, this is gonna sting) a tie for number 3 with Lasker, and argues that the two-headed Kasparov/Karpov monster is the dominating #1 #2 of all time. They are near each other, but otherwise the pair utterly and convincingly dominate the remainder or their contemporaries for nearly two decades. -- pretend either Karpov, or Kasparov gets dropped on his head, age 2... and the other one suddenly stands out as a leviathan.
Reasonable people can and do disagree.
