Honestly, if you can manage wall or ceiling mounted speakers as opposed to Atmos modules you’re better off in my experience. I’ve tried Martin Logan, Def Tech, PSB and Klipsch Atmos modules with 10’ ceilings that are flat and not vaulted and at the end of the day I’ve gotten exponentially better 5.4.4 performance simply using two pairs of Definitive Technology ProMonitor 1000’s I grabbed off Craigslist for $100 a pair.
