One factor that the poster Judom brought up: women's Olympic Judo is contested far more fiercely than women's wrestling. It has been around longer, attracts better athletes, and has a much better development program.
This isn't about style v. style so much as it's closer to comparing an NFL football player with a D1 basketball player. Comparing a men's Olympic wrestling medalist and an Olympic judo medalist is a very different calculation.
Just one thing to consider.
