Hi. Sorry for the late reply. The answer is yes, this is a good TV to consider for the PS5.
However currently, with the latest firmware, the Sony X900H is using a processor that seems, as of now, is incapable of processing 4K at 120Hz. So what is does it take the 4K 120Hz signal via HDMI 2.1 and downsamples it to 1080p 120Hz during the processing part and outputs a blurry 1080p 120Hz mess.
Something to take note of if you are planning to get this TV for your PS5 or XSX or PC with next gen HDMI 2.1 cards.
The result of the downsampling of the visuals can be seen here.

But... Sony has now released a statement that they call this issue a firmware bug so it could be fixed in the future. So best advice is, set your output to 4K 60Hz with this TV. Until a new update that addresses this issue is out.
Considering, there aren't much games running above 60fps on the PS5 now, it is a win-win situation. So sure. You can get this TV and hopefully get the fix in the future and enjoy 4K 120Hz.
