I highly recommend both of those. If you like Durarara, then Baccano is probably up your alley. I haven't actually seen Durarara yet, but they were created by the same person.
I absolutely hated the ending of the show, but the movie End of Evangelion saved it for me. If you haven't seen it and you like the weird, mysterious parts of NGE, then I recommend that too. It's a fantastic late Friday/Saturday night movie, and it kept me awake the following night trying to comprehend what I had just watched. XD
Even for a parody of fanservicey anime, Kill la Kill does occasionally take it too far. lol But by the end of it I hardly even considered it fanservice since they did a pretty good job of explaining WHY the suits had to look like that.
I didn't watch '03 because I was told Brotherhood is better. And it follows the manga plot, so I would automatically be a bit biased against it because I'm kind of trained to dislike filler or anything the manga author didn't write personally. Mostly because of shows like Naruto. Not that that's been exactly good lately.
AoT isn't one of my all time favorites, but the world really intrigues me, and they're really good at creating suspense. Plus the animation is gorgeous. My main complaint is it's just so freaking slow. I don't want to hear these minor characters we won't see again complaining about how they're going to die every 5 minutes. It's bad enough hearing the main characters complain about it.
Oh wow, so you stopped right when... well, I won't say in case you didn't actually finish episode 8. If you did then you should know what I'm referring to. XD But that really sucks that they ruined it for you. I hope you are able to watch it again some day because the climax is fantastic.
I've heard a bit about Ping Pong the Animation. It seems......... bizarre to say the least. XD
Rei (Free!), Kyoko (Dangan Ronpa), Yukine (Noragami), Akihito (Beyond the Boundary), Kaworu (NGE), Inumuta (Kill la Kill), Volkner (Pokemon), Kyoko (PMMM), Jean (Attack on Titan). I know a couple more by face and franchise but I haven't gotten into those.
