I'm going to give 4, because I think they all deserve a mention.

1.) Prison School - Outrageous cast of characters, outrageous situations. Easily competes for best comedy ever. Fantastic voice casting. When they talk about "serious comedy" in Bakuman, this is it.

2.) GATE - Interesting concept, fun characters with Rory and Lelei. I really enjoy watching the cross-culture exchange and extremely weird politics between Japan and the fantasy world.

3.) Symphogear GX - If you like battle heavy magical girls and are not watching Symphogear, you're missing out. This season started with a bang, perhaps the best episode 1 of any show this season. They continued to deliver up until a couple episodes ago where the writing took a bit of a nosedive. I'm hoping they can save it with the finale, but at least the singing and battles are still awesome.

4.) Rokka no Yuusha - While I can't say the mystery was completely satisfying, Rokka entertained throughout all of its episodes and kept a nice pace of action and mystery combined with mostly good animation. It definitely left me wanting to see more of Adlet and crew.

Honorable Mentions: Overlord, Shimoneta (OMG, craziest character ever in this show), Sore ga Seiyuu,
