It's been a couple of years since I don't really put myself to just watch anime for fun, and I have a really bad memory but I'll try my best.
I think that my favorite anime is Hugurashi no Naku Koro Ni, it just blew my mind! It's an excellent one! It has an enormous psychological background and it just plays with your mind so beautifully that you just want more of it, and it's actually a really large one, it has 9 parts I think, and the saddest thing is that I haven't finished it yet, but is definitely a good one.
When it comes to romance I'm going to go with Toradora! I just loved it, it has the right amount of comedy, romance and high school life that you need in an anime.
I also really liked Kuroshitsuji a lot, I have watched three times already and I never get bored of it, for me it was extremely interesting and beautiful.
My list is too short... I really need to start watching anime more often again.
