Unless, what's your take on Mecha anime? You can try Macross Frontier, or Tengen Toppa Gurren Lagann - and moving away from mecha you can try Soul Eater.
Seen all three and I do like my mecha amine also seen gundam 00 and season 2, gundam seed and destiny would like to get hold of the older versions of gundam series.

Gurren Lagann especially because they didn't stick to the normal conventions
If you liked Gurren Lagenn anime stile and insanity of action you should watch Needless
