By your list, Waldner had Primorac, Gatien, Yan Sen, all at the top of their game at the time. Wang Liqin had not yet peaked and Ding Son was a defender. Pure defenders have never breached the very top of TT since the invention of the loop. OK, Schoeler just lost on a net ball.
I'd say they both had it about even with Waldner having it slightly easier on paper.
But the fact was that Samsonov was playing some unbelievable TT at that time also, he was the world's best player at the tournament. He just came across a Waldner in his best ever form.
