Vortex Sound Research

Exactly as in the title, which do y'all think would be better? I know there really is now right answer, but I want some input on other people's thoughts. I like Komplete for the vast library of sounds, but I'm looking at the prologue/DSI rev 2 and oh man they sound fantastic and seem really fun to play with.

Currently I have a Moog Grandmother, Boog Model D, and Novation Circuit I use with Ableton Live Suite.
