The stories are not very alike but they both have supernatural elements. Majin Tantei Nougami Neuro with, it's wonderfully funny sadistic demon and Soul Eater, with it's witches and people being about to change into weapons. If you like one you'll like the other is that the art styles are similar. Not exact but close enough to remind me of each other when reading.
