My favorites are Spice and Wolf and Fullmetal Alchemist (both original and Brotherhood), and Death Note is also pretty high up there.
I've been watching a lot more since picking up Netflix; also the library in the town I moved to has quite a respectable-sized manga section (two actually – a YA section and an adult section) so I can start reading more. I just read volume 1 of Claymore.
Currently I'm watching Naruto; I'm about at the point I once read up to in the manga (the chunin exams) and farther than I'd previously gotten in the anime. Also Pokemon; I'd watched up to Johto Journeys when I was a kid and am now re-watching, in order, as they become available on the Pokemon site.
