In my opinion, the differnce can be summed up like this:

Men are looking for a reason to accept the girl. Women are looking for a reason to reject the guy.

It seems us men will often say something like, "Yeah her face is ok but her body is fine and she's cool". Or "She's a little thick but she's got nice tits and a nice ass".

Women are like the opposite always screening out. "Yeah, he's handsome, and fit, but his job isn't good" or "yeah he's not too bad looking and has a good job but he's not tall enough".
