I've started manga recently as the anime I'm watching aren't all that interesting. It has its ups and downs. Manga stories feel much shorter (in absence of fillers, etc) and seem to end abruptly. However, it's nice to read something that's right to the point and still interesting.
I tried to read Air Gear but...it's fucking roller skates and a guy who beats people up while using them. Not much more to it -_- I couldn't get into it at all, stopped about 10-20 chapters in.
