On an unrelated matter, I have been testing DTS headphones X and Dolby Atmos in some single player games (on PC). My initial tests were using the Witcher 3, and I was ready to conclude that DTS was superior, as you get a really balanced presentation and a huge sense of spatial depth which really shines with all of the game's different environments (caves, cellars, forests, riversides). Voices are very clear, although everything lacks a bit of bass. Dolby Atmos sounds much more spatially compressed and voices have depth and bass, but they sound a bit harsh.
However, I then tested two other native Dolby Atmos games, Shadow of the Tomb Raider and Metro Exodus. In both cases, Dolby Atmos was far superior, and the sound mix of the games, specially Shadow of the Tomb Raider, is nothing but amazing, specially in the jungle environments where you can hear all the animals buzzing and chirping around you. Metro Exodus can also be really impressive too, like when you shoot a shotgun you can hear the loud bassy boom initially and then the echo as it reverberates in the environment, it's insanely realistic. DTS sounds like a cheap reverb filter in comparison in both games.
So my conclusion is simply that some spatial filters sound better in some games than others, and ideally you could own both and use them accordingly. My theory is that DTS will work better in games that don't have a very good spatial mix (so it might 'fake' it better) or in games mixed natively for DTS, but Dolby Atmos will work better for games that have a 'native' Dolby Atmos fix, which there are more of.
However, I already own Dolby Atmos, and DTS is a bit pricey ($20), so I might wait until there is some sort of sale to buy it.
