They both feature a socially awkward main character with very few friends. The amount of cringe moments is respectively high in both anime, and while not necessarily bad, if you don't mind it in one you shouldn't mind it in the other. You'll find yourself wishing you could make decisions in place of the main characters as you watch them fail miserably at the simplest tasks; however, Watamote uses a more comedic approach where Aku no Hana was dark and almost nihilistic with its atmosphere.
