Simply the best on all surfaces and in all conditions. Her forehand remains the single most dominant shot in the history of tennis and her athleticism was incredible. Monica Seles was incredible, but had a loosing win-loss record against Graf BEFORE the stabbing as well as after, so she can hardly be regarded as superior to Graf. Seles never won Wimbledon either. Natratilova was great, but Graf made her look slow. I would be intrigued to know how Graf and Serena Williams would compete against each other, at their best - two wonderful athletes with different power games. I think mentally Graf was rock-solid and her confidence deep-set. The game misses her. I think Alicia Molik has watched a few Steffi Graf matches too.
