Let's see... I still haven't tried everything I intend to, but here are my opinions so far:
Mayo Chiki - After the first 5 minutes I already knew I wouldn't like it, so I stopped right there. There's something about the concept and storytelling style that I just don't like.
Itsuka Tenma no Kuro Usagi - I've read a few chapters of the manga, so I already knew the story starts interesting. It's not great, but it's above my dropping line.
Dantalian no Shoka - One of the best of the season. Reminds me of Gosick, only with none of its weaknesses.
Kamisama no Memo-chou - This one reminds me of Gosick, too, lol. Far higher quality mysteries, though. The characters, unfortunately, are only so-so.
Ikoku Meiro no Croisée - Cute, great backgrounds, but at least the first episode was slightly boring. Stalled it, I'll need to be in a very special mood to really enjoy something like this.
Nurarihyon no Mago S2 - I'm really annoyed that they skipped the Jami arc, but otherwise it starts with the same great quality that marked the first season.
Sacred Seven - Hardly a quality anime, but it's great light entertainment to me, so it's actually one of my most anticipated anime each week.
Usagi Drop - I'll marathon it once it's complete, to take the most enjoyment out of it. I've read the pre-timeskip part of the manga, and it's one of my top favourites, so I'm expecting this anime to be my favourite of the season.
Ao no Exorcist - It was a bit meh for a while after the start, but the last few episodes have been great again.
