I think I'm fine with the (pseudo)underline for h2, but the under/overlining of h5 makes it stand out more than h3-4.
By the time someone gets to h6, I don't think much distinction really needs to be made; boldface but otherwise p-style would be nearly enough. (Since you pointed out wikipedia's, note that h4-h6 are all the same, and h3 only differs from those in font-size.)
