Both have the same author and thus are drawn in a similar style. They also both have fairly strong plots, and feature supernatural beings such as ghosts and demons. The primary difference is that The Demon Ororon is a longer, more involved story than Baku, which is basically a volume of short stories. I enjoyed both of them very much.
