Most Helpful Guy
If a guy has money or power or whatever, it probably doesn't matter what he looks like. He'll probably be able to get someone most would think is too attractive for him based on looks anyways.
One the other hand, while guys don't generally have as many factors that go into what makes them consider dating a girl (physical attraction eats up a larger chunk of the pie), guys still want to get laid so they'll tend to lower the bar quicker in order to accomplish this goal.
It's probably ultimately somewhat equal.
