PS4 Pro optical audio: DTS vs Dolby

I have my PS4 Pro connected to my 5.1 speakers (Z906) via optical, so I understand that due to bandwidth limitation of the optical cable I cannot get PCM Linear 5.1.

As such, which is better? Dolby or DTS?

@GhoX: DTS

DTS if your sound system supports it

Cheers. DTS it is. Mine supports both Dolby and DTS.

Enjoy :)
