FWIW, if Brown hadn't called, I would have been pretty happy hanging my hat at Omni for life. It's a hell of a lot better than the best 135 I ever heard of, let alone worked for. IMHO, it's the best-kept "secret" in long-haul for a lazy bastard (like me). Sure, you'll never break guarantee, but that's a good thing if you're flying ~25 (my average) for 64 hours of pay. When I'm locked in a Shenzhen hotel room with some ChiCom Enforcer sitting outside with bayonet fixed I sometimes hanker for those simpler times when I was hanging out at home wondering why the phone never rang.
Wherever you go, even if it's Atlas, I sincerely doubt you'll regret the change. Do it.
