DOLBY ATMOS - DTS:X

Dolby Atmos is very similar to DTS:X, but the technology itself is quite different. Both Atmos and DTS:X are object-based surround sound technologies, but Atmos puts more emphasis on height – so much so that Dolby recommends you install ceiling speakers to get the full benefit.

A 5.1 system (made up of five satellites and one subwoofer) with four Dolby Atmos speakers would be referred to as 5.1.4. 7.1.4 is the reference set-up for Dolby Atmos – in other words, the tech runs natively on a set-up comprising seven satellites, one sub and four Atmos speakers.

DTS:X has the edge in terms of sound quality because it supports higher bit rates - Dolby Atmos codecs are more efficient than DTS-X hence sound comparable or even better at a lower bit rate
