Sorry I dont have any experience with the omni channel. It looks nice though. I'm sure it does very well. I use Scheps Parallel Particles, and its nice to glue a track together. Scheps is a great inspiration, and I think anything developed with him is propably super!
On the bx_consoles though, I can say they sound great. I like the instant musicality and fullness of sound that you get from using brainworx console emulations. Ive purchased a few bx plugins and like them all. I'd go brainworx over waves after trying several products from each. Just my personal preference though.
