I've been watching like… one anime a year recently, but Back In The Day (when I read/watched tv more in general) I had a real list:
– Rurouni Kenshin was my fave (all of the manga, first season of the anime)
– Busou Renkin (manga and anime)
– Wolf's Rain (+ manga adaptation)
– a long long time ago I watched Evangelion (none of the movies I don't think), Trigun, and the original FMA, but I barely remember most of them
– Madoka Magica I watched only a year or two ago actually
– and of course bits of things like Inuyasha and Bleach and Naruto that used to be on tv, but I didn't seriously keep up with them
– also for manga-only, I collected all of +Anima years ago, again don't remember a lot of it
– and I used to follow Kaze Hikaru but they've gotten so difficult to find I don't know if I'll ever finish it
I really need to rewatch/reread a lot of this stuff (Wolf's Rain and Busou Renkin especially) and watch Brotherhood someday but I'm terrible at starting things
the only thing I've been into recently is Noragami… I watched it over the course of several months last fall, then picked up a manga volume a month ago just for kicks and got sucked in because it's so much more detailed than the anime. I'm probably going to look for the rest of the volumes as they come out so hopefully I'll be relatively caught up when the second season airs (it focuses on my favorite characters this time!!)
other than that, most of what I follow nowadays is video game adaptations. a lot of the big Tales Of games get a short manga series or OVA, and Tales of the Abyss even got a full 26ep anime. unfortunately the anime generally get only subs, and the manga haven't been localized at all, so they're kind of hard to find…
