Kill la Kill is completed... great damn anime. Easily my second-favorite, dethroning Steins;Gate. Yes, second place has its own throne, since Gurren Lagann is, in my books, its own kingdom and probably won't get taken over anytime soon, so the second place category owns the thrown. 
There were a few minor problems I had with the show to be sure, such as some instances of odd animation, there were times the fanservice was just too much even if most of it was part of the point of the show, and some other minor things, but there was just so much more that made up for it, with great characters, art direction, music, story, and humor. It maybe too closely followed in its big brother Gurren Lagann's footsteps at times, but it still has an identity all its own, and more of that show's pure awesomeness is always welcome. Studio Trigger is off to a great start with a very tough act to follow, and I wish them the best luck in the future. (yes I know they made Little Witch Academia before Kill la Kill but that wasn't a full series so it doesn't count)
As for what's next? I'm about halfway into Baccano! and so far it's alright, though I feel like I'm waiting for pieces to fall into place before I can fully appreciate it. After that is Cowboy Bebop, since it's so well-loved and I figured I might as well look into it, especially since it's shorter than I thought; for some reason I thought it was one of those long-running shows I didn't want to touch, but thank God it isn't.
Now that Log Horizon's complete, I too will be checking that out after these shows, because I loved Sword Art Online's concept and would love to see a similar concept executed correctly, instead of the disappointing mess that was SAO.
