My fav is Omnisphere from Spectrasonics.
Its so versatile! You get tons of playable patches like pads, leads, basses, all sorts of organs, some otherwordly pianos and rhodes, strings, bells, great choirs and nice guitars.
It also comes with a lot of ambience stuff that you might consider to be weird and too electronic but thats just a part of the big package and definetly comes in handy for intros, breakdowns and transitions
More than 2000 sounds already and more free ones are in the works-so you should be able to find something you can use.
If you want to hear what it sounds like check my vimeo link in my signature.
I made a whole bunch of videoclips that use Omnisphere for the soundtracks.
Maybe it floats your boat!
