Most Helpful Girl
If we're talking physic, it's easily men. Because aside from their looks they have many fall backs. Society values more the importance of a woman's beauty.
In terms of money, career "social class" it's easily women.6
Most Helpful Guy
I think women -- broad generalization but often they seem to go for guys who are taller, stronger, smarter, faster, better job, more mature, more famous, etc. (not all of the above but perhaps some at least).
With guys -- dumber, worse jobs, less mature, not as famous, not as ambitious, etc.
The only case where this doesn't apply is looks, perhaps, but I'm considering "league" as an overall package. Women usually pick men they can look up to, men often follow whatever women pick.
Hope that's not offensive, just the way it seems the world works to me.8
