Exterminate!
dts:X is the other - at least for movies I’ve personally not heard a dts:X example yet and my AVP isn’t compatible with it.
Look at all of the 4K UHD Blurays coming out now - a bunch of them have a Dolby Atmos soundtrack.
Dolby Atmos is also epic for multi-ch music - Roger Waters’ The Wall being the best example I own. Apparently it was to be recorded in Atmos from the word go.
So it looks like Atmos is the winner. Dolby pretty much has a lock on the market anyway, which frankly is one place I'm glad to have a monopoly. I would hate to give up my beloved B&K Reference 50 but it would still be used to power the sound for the massive man-cave gaming rig.
