I liked RahXephon. I've seen some epic arguments about that show on forums, apparently there's a massive geek war going on between RahXephon fans and Evangelion fans.
I most recently watched the Crest/Banner of the Stars series and I liked that a lot. It's a futuristic sci-fi deal with space war and romance mixed in and I think it's really more of a drama than anything, but it's all handled very well. The characters are pretty good and despite the theme they seem more realistic than many other shows.
