For someone of height, Justine's overachieved in her career. So I think she's more talent.
I define "talent" as been related to size/physical strength. Because let's face it, tennis is a VERY physical sport. IMO, someone like Davenport/Venus should achieve a lot more than say Hingis/Justine because they're taller, has longer reach, stronger, etc...
The fact that Justine has 3 slams in the last year means she's taken her physical limitations out of the equation and used her talent to make an excellent career for herself. She doesn't look that strong either.
