Not a Henin fan but how on earth is Henin "nowhere near Seles"?
Henin is better on clay and grass, 2 of the 3 major surfaces. Seles only better on hard courts, 1 of the 3. And even there really only slow to medium hard courts, Henin is as good or better on medium to fast ones.
Henin was the World's best player 4 years- 2003, 2004, 2006, 2007. Seles was a mere 2 years, 1991 and 1992.
Henin faced a way tougher field. She faced the Williams, Clijsters, Davenport, Hingis, Sharapova, all at their best. Seles by contrast faced only Graf during her couple yeras on top, and Graf in a bad slump and barely even reaching Seles (although usually beating Seles when they did play). Wasn't a nearly 40 year old Navratilova the World #3 most of that period, LOL! Then when Seles returned and the field was tougher and the big hitters like the players I mentioned had emerged, Seles didn't win hardly anything. Just imagine what Henin at her peak would have done against a super weak field like Seles had in 91 and 92 where she playing Sanchez, Sabatini, Mary Joe Fernandez, Anke Huber and a grandma Navratilova in all her slam finals. Henin of 2003, 2006, 2007 replacing Seles and facing the same garbage field Seles did in 91 and 92 where she faced Mary Joe freaking Fernandez in about half the slams she won in the semis or finals, probably does atleast 1 Calendar Grand Slam which Seles still never managed. Like seriously do you think if Henin played Fernandez 20 times she would lose even once? Yet that was one of Seles's biggest rivals in 91 and 92 during her dominance.
Seles has 2 more slams, that is her biggest edge, hardly enough on its own to say nowhere near. Henin has the Olympic Gold, and both have multiple YEC titles. I put Henin ahead in time at #1, since she has 3 YE#1s (should be 4, since she was clearly the best in 2004 despite the rankings) vs 2 for Seles- 91 and 92. Seles technically has more weeks but given that she was given 60 free weeks by a stupid ranking provision in late 95-96 where it was ruled she would be "co #1" no matter her results the first over year of her comeback and in reality was never the best or would have been ranked #1 otherwise, and that Henin took herself off the computer by her own choice which cost her about another 15 weeks at #1 even while not playing based on all the points she had, Henin should be ahead even in that.
I could say Seles maybe ranking higher, but it would be just barely if she does.
Now if you said Goolagong being nowhere near Seles, Henin, or Venus, that would be an accurate statement. The 4 people who voted Goolagong best on this poll should be banned from the site for epic stupidity. I am an older tennis fan and not stupid like many of the youngings here (I am guessing the 4 people who voted Goolagong best are all 15 years old or younger and Australian and picked her by watching youtube highlights), and I know Goolagong while beautiful to watch and super talented, and a gem of a human being, was an inconsistent headcase who even when she played well was simply a perennial bridesmaid over and over again to Court, King, and a young Evert. And that her slam count was padded by the then illegitimate Australian Open, an even won by the world #111 Chris O Neill once, a player with a 19-52 career WTA record. Draw your own conclusions on the Australian Open worth back then. Never a dominant player like Venus, Seles, Henin all were by any stretch. Yes she might have a "prettier" game than those 3, and she might be a nicer person, but that is not what tennis greatness is about.
