In general, Dolby Atmos is regarded as the gold standard for immersive home audio technology. That said, different audio formats like the Auro-3D and DTS:X also provide good quality and object-based sound like Atmos. It is also important to remember that "better" can be quite subjective, depending on the individual's preferences, audio setup, room acoustics, and the content available. So, you must always consider these factors while concluding what's the "best" sound system for you.
