I'm currently using Nova, but you could also try Apex or Holo Launcher. Those 3 are all essentially the same, they just have slight differences between them. They try to emulate the Jelly Bean look.
Other than that, Launcher 8 comes to mind. It tries to look like a Windows Phone. I didn't like it, but you could always try.
I can't think of any other launchers, but I'm sure there's more.
