I think the season's off to a good start. Some of my favorites so far:
Monogatari S2, Symphogear G, Senyuu 2 and Teekyuu 2. No surprises here, they are all sequels to stuff I liked and they didn't disappoint.
If you haven't seen Senyuu or Teekyuu, they're both on Crunchyroll with episode lengths of >5 minutes so they're easy to check out. They're both comedies, Senyuu has a fantasy setting and a storyline where Teekyuu's story is as elaborate as it's premise (high school girls in a tennis club (though they don't actually play tennis much))
As for new shows, Uchouten Kazoku and Gatchaman. I like pretty much everything about Uchouten Kazoku, especially the characters and art. I was curious after ep1 and sold after ep2. Gatchaman has Hajime. I'm still not sure what the show's actually like though. Monster of the week style? At any rate I really want to see more episodes of both. Oh, I'm really enjoying C3 as well.
