Vocal Atmospheres by Cory Friesenhan is great for pads.
Siren by Veela is one of their best.
As one who has acquired many loops I find it hard to fork over that kind of money for loops. With subs you start hoarding. If you think the VST market is competitive it's greater in the loops field. I've found smaller producers and smaller packages to have more usable content that come with presets and midis.
