I have the middle one. But the only reason I tie it up high is because my hair is long and gets pretty messy. I never understood people who can bear to tie their hair low eg the first from the right. Because I get hot and bothered with the hair behind my neck and it really depends as well the place you are from. Where I am from, it is a hot climate all year round. The first two is just dumb but the other 3, I don't see how intelligence and the angle correlates. Also, I have encountered peers with hair tied like the first from the right but are deemed messy and prove this theory (at least for the three) is pretty baseless and done just to target at ppl with he first two hairstyles.
