Both titles are about the Shinsengumi in the same era of Japan's history. A handful of the characters are featured in both works, so it's interesting seeing the same historic people portrayed differently.

Jyuushin Enbu and Yuu Yuu Hakusho both portray martial arts in cool fictional fashions. Yuu Yuu Hakusho focuses on spirit energy, whereas Jyuushin Enbu focuses on Souhiki Naiden (called something like that, I probably screwed the name up though.)

Juushin Enbu: Hero Tales

Well, they aren't all that similar in their plots or details, just the fact that they both have action and are shounen. The reason why I recommend watching Juushin Enbu if you like FMA though, or vice versa, is because both are created by Hiromu Arakawa. So if you like one of her creations, you'll probably like the other.

Both are of course great mystery and detective shows. One thing I see that is kinda similar in the two series though is that Neuro basically uses Yako to solve cases in Majin Tantei Nougami Neuro, and in Detective Conan, Conan uses Kogoro. So it's like both detectives use others to solve cases. Majin Tantei Nougami Neuro gives a lot more of a supernatural feeling though, whereas Detective Conan is a pretty much straight mystery series. So that certainly gives enough difference between the two for entertainment.
