Not trying to defend SONY in any way, shape, or form, as I believe that Microsoft's offering will be as quiet as it seems to be powerful, but there's something we need to consider - you can't have audio being one of your core features for this generation, and yet have a loud console. This is why I think SONY went for a console that doesn't push itself extremely hard to reach a TF count that, from SONY's standpoint, serves them no purpose (increased graphical fidelity in this era of diminishing returns).
Going for a 9.2TF console that, if needed, pushes itself to 10.28TF is perhaps the balance they struck between having a whisper quiet console that delivers on sound but also performance.
What remains to be seen is if Microsoft's Series X manages to deliver on all 3 without the power compromise of SONY.
Hopefully, multiplatforms don't take as hard a hit as they did back on the PS3 vs. 360 generation. I hated having inferior multiplatforms, but the PS3's exclusives were more appealing to me at the time.
