What anime should I watch next?

Definitely don't listen to AnkA, he's absolutely wrong, I don't think you'd like them at all. I'd say that Blood the Last Vampire would be good for you. It has great action and very good character development. It's like Trinity Blood but more possible, and definitely keeps you watching. Only thing it doesn't have any comedy in it, and it's rated TVMA, but if you want some comedy to throw into it watch the filler episodes of Prince of Tennis, they're hilarious.
