I also prefer manga Tanith. I don't own many; there's most of Rurouni Kenshin, a start of JoJo's Bizarre Adventure, and recently found one of Tatsumi's books.
I've already read all of the completed parts comprising JoJo, and I'd say it's my favourite series (it's where my first avatar was from). It's just been so long since I read Part 3 Stardust Crusaders that I figure why not. XD
Riki-Oh, where my current avatar is from, might be my second. It's pretty much a 'clean' Hokuto no Ken, and yes, directly inspired that notorious HK movie, Story of Ricky.
Well anyway, I am into the "Big 3" (except for One Piece), but I will probably wait now until they're finished.
Last series I read was Pretty Face. It was kinda interesting, but maybe because I read it rather quickly I don't remember it that well, IDK (I also didn't care for a lot of the goofiness). But I think I like it better than Mx0.
Currently I'm reading Death Note (I've only seen the dub of the anime so far). I'm just glad my area's library system has most of the volumes (and probably the one series they've got I'm interested in).
