I love both Jana and Gabby but there is not doubt here that Gabby was better in almost all aspects!
Gabby Sabatini has less money because most of her success came from (87-92), Jana's success came later on (93-98), the word we are looking for is inflation. She earned more, because she got paid more, its as simple as that.
Not to mention Jana played longer.
By the way Gabby Leads the head to head 10-3, with their last 4 out of 5 being straight set wins for her.
Career Win/Loss record is 632/189 compared to Jana who is 571/225.
Gabby not only has won much bigger titles in her career but she has 27 to Jana's 24 titles. Gabby has reached the grand slam QF 28 times, the semifinals 18 times, and the finals 3 times.
Jana has reached the QF 22 times, SF 8 times, and the finals 4 times.
Gabby has 2 YEC titles, reached the finals 4 times, and the semis 7 times.
Jana has won 1 YEC, reached only 1 final and reached the Semis 3 times.
And lets not even go into their head to head records against Graf and the rest of the pack.
Gabby has beaten Steffi 11 times, more than any other player and well Jana has beaten her 4 times out of 33 tries.
Gabby has beaten Navratilova 6 times and Jana has beaten her only once.
Both ladies had great careers and failed to live up to their full potential but Gabby is the winner here!!!
