Are girls or guys harsher when it comes to judging a persons looks?

I think girls are way harsher. 1st of all if a girl sees a picture of a pretty girl chances are she will be Catty and say something snippy to her to make her feel ugly. Girls are very jealous. Also if that isn't the case girls can see the tiniest flaw in anyone!! Guys I know most just look at the rack and and that is how they judge. But I think they also do look at the whole package. I think guys are easier to please
