I've been watching Noragami (translation: Stray Gods) and I really love it. I have been following the manga long before, and I was excited when the anime was announced. Sadly, it's a 12 episode series and diverges from the manga--but I still love it. It's the sort of relationship I have with Studio Ghibli's Howl's Moving Castle and Diana Wynne Jones novel: I love them both, but they are not the same story.
I also liked Sword Art Online. I'm not sure if they've started--or plan to start--Gun Gale Online but I'm really looking forward to this possibility.
Cowboy Bebop, Full Metal Alchemist, Full Metal Alchemist: Brotherhood, Trigun, Kimi ni Todoke, Suzumiya Haruhi no Yuutsu, and Yu Yu Hakusho are to this day some of my all-time favourite anime
