I know what you mean, I guess it's like saying it's more advantageous to be poor than to be rich because when you're rich, you'll never know who your true friends are unlike when you're poor or broke or bankrupt then you'll know who still likes you and would stick with you in spite of your circumstances.
I have nothing against good looks however I'm guilty of not taking them seriously and stereotyping them as not that intelligent. I'm not shallow but it would be a lie if I say that appearances don't matter because I have got two eyes and the physical appearance is the first thing I notice whenever I would meet someone. Beauty is also relative so what may be attractive to you may not be attractive to me and vice versa.
