I realise this issue has probably been touched upon many times on this forum previously, but I am genuinely curious as to people's thoughts.
Seriously, I can't see how anyone can logically say Serena is a better player than Henin was by the end of her career.
Consider that it is far likelier that the limitation lies with you, rather than others. YOU can't see it. Fine. But 11 slam singles titles > 7 slam singles titles is a difficult arguement to overcome.
As for your other arguements, your problem is that you're trying to relegate the arguement to a narrow period in the careers of two players of roughly equal age. If I narrow the arguement to 2002-3, Henin had already made a lam final by then, but who was having better results? Or, to take two other players, who was better in 2006? Elena Dementieva or Venus Williams?
Had your statement been, 'there was a period in Justine Henin's career when she was better than Serena'
I would have to agree. This is also true of Venus, Jennifer Capriati,Martina Hingis and Amelie Mauresmo. They all had periods, lasting a year or more, than they were better than Serena. AFTER Serena won her first slam. The difference with Henin is that when she saw she wans't going to be the best anymore, she retired.
Serena has persevered through every period of somebody else seeming better for a while. And look who's on top now.
movement-wise Henin was infinitely better,
I could as easily change that statement to 'Serena was infinitely better'.NOTE:
in 2007, Serena simply had no idea how to beat Henin
In 2008, she beat Henin 6-2 6-0, possibly contributing to Henin decision to retire instead of finding her game again.
