The anime is pretty good, but is missing a lot of the charm. Plus season one diverges from the manga and has an anime original ending that's... well, it's bad. But then they retconned it for season two which covers the Kyoto saga and again it's good. But it's missing that charm.
Personally like most series, the manga is better. Especially after Kyoto, the Illuminati really kicks it up a notch, at least for me.
