Waw... A 3 years old thread and there are still answers '-'
I'll take Log Horizon (seriously though, I prefer this over those two).
Sure, SAO's second half............ Well, only its first quarter was fine (or an eighth of it, whatever) but at least to me, it's better than the latter which didn't catch more of my attention after reading its summary.

SAO got me pretty bad so now I'm pretty much a fanboy for it.
Attack on Titan was really great and I really enjoyed it. The only problem was the long wait for S2 and the manga was going at a pretty slow pace so I just stopped reading it. I'm sure I'll love AoT again since I have a lot of material to catch up on.
