Well, depends on what you like.
The only thing I'm certain they have that's good is Afro Samurai, which is mostly just an entertaining, very bloody hack 'em up (it does have some depth, just not a lot). Resurrection is considerably worse, sadly.
I think they might have Samurai Champloo, which is somewhat similar but a lot longer, more plot-containing, and with less blood. I'd pretty much recommend it to anyone, unlike Afro Samurai, but again I'm not sure if they have it.
They've also got Samurai Seven, which is an over-the-top anime adaptation of Seven Samurai featuring giant mechs and robots. I liked it, but depending on this and that it might not be your thing.
Finally, there's Casshern. I'm honestly not even sure why I like it, and it's got a lot of tropes I'm sure are very easy to hate (amnesiac regenerating hero who goes into a berserk kill-frenzy when pushed too far, wandering world trying to figure out what went wrong angst etc). It's got a very retro feel to it, somehow, with the main character's outfit reminding me a lot of Speed Racer. Anyway, I like it, but that's probably extremely a matter of taste.
Also, if you meant Clannad, Hetalia, and Queensblade were things you've already seen and liked, you might like Witchblade and/or Claymore. They're both fanservicey action things, though I hear Witchblade does have some semblance of a plot to it.
