Seinen are most mangas I can relate to the most, the variety of choices is also a plus, I also like to read some shounen, the stories have a similar aspect of developing there, but there are some pretty good ones that take some more mature turn.
I rarely read the others, but when I do () I usually pick up something that is close to what some seinens or shounens are, for example some good josei series come rather close.
