We have only a handful of crossplat titles where comparisons can be made and differences are not that jarring. Sony has a lead as its SDK is reportedly more robust and more intuitive at the moment but Microsoft will eventually catch up - since Nadella became CEO all of their dev tools have been world class.
In 2022, after half a cycle, we can once again compare notes on how/whether the PS5 is "superior in ways that have not been communicated". This is the same garbage we hear every console cycle - "blast processing", "the reality synthesizer", "the emotion engine", "the Cell, a supercomputer on a die", etc.
We actually do know where the PS5 is superior: faster i/o speeds, haptic feedback (a game changer), VR backwards-compatibility. As for raw power, the XSX is the superior machine and in the coming years, as more tools come out, documentation is streamlined, etc., that will be ascertained. Same thing happened two generations ago: The Cell was a better processor than the Xenon, but that only really became apparent towards the end of that generation once Cell's complexity was fully understood by all major developers.
This is not rocket science, both consoles have RDNA2 Radeon GPUs and the SX GPU is more powerful. It is what it is, folks. Whether that makes the Series X "better" (a childish notion, but console warring seems to be reaching embarrassing levels) or "worse", well, that's for you to decide.
