I'm late to the party here. I only ever heard great things about Elfin so I expected real fall out from the bash on it. Glad I never got around to it no from what was said because it really wasn't my cup of tea. Even as a teen, I always though random needless nudity was just a lure for me and the rest of my demographic and really cheapen the experience for me.
A series I loved on IFC channel was Speed Grapher. Here's trailer vid below, but essentially the gist of it is a war photographer turned reported finds his way into a seedy underground sex club for the ultra- rich and elite. When there He interrupts a ritual where a "goddess" is supposed to be bestowing a man with powers and instead, the reporter gains them.The powers gained are directly tied to "what the host wants most in their heart" so plenty of diverse enemies show up through the series. Good violence, not overly sexed up (especially considering how ther series starts in an underground sex club)
And when in doubt, always Evangelion. Though, it gets a bit too sureal in a few fillery episodes. A series I liked recently which is a nice half way point between Evangelion and the Xenosaga games, is Knights of Sidonia. Think it's a netflix exclusive. Season 1 was better, but there are 2 seasons available.
Here's the opening for season 2, I found it more exciting than the official trailers:
