You should probably watch Gurren Lagann.
I watched the first episode of Kill La Kill and didn't watch anymore. I wasn't really in the mood for something that moved at a breakneck pace and I'm probably still not. I like quiet moments.
EDIT: Also, in the middle of all the Gurren Lagann and Cowboy Bebop recommendations, I'm going to tell you that you must watch Baccano. I've seen that anime several times and I always pick up on something new, and what I have already picked up on is still incredibly entertaining. It's basically what would happen if Tarantino wrote a screenplay about robbing trains and then told an anime studio to see how fucking nuts they could make the whole goddamn thing. And that's really not all there is to it, just watch it.
I didn't really enjoy Gurren Lagann that much. I really enjoyed Kill La Kill so I watched Gurren Lagann all the way through but it just didn't click with me. Kill La Kill on the other hand was hilarious and had some pretty great moments throughout. I might rewatch it now there is an english version.
