I think you've listed the majority of the benefits. As someone who is looking to investing into a PC maybe a year from now, I'm not sure is a series s/PC is the play or a series X/PC. My biggest issue is storage I guess, if the series s had like 750gb it would be a no-brainer
Main reason why is because I have a sibling that prefers PC over consoles, personally I don't care too much
Keep in mind the Series S is supposed to have game file sizes that are 30% smaller on average, so the SSD is potentially more around 665GB relative to the Series X (if my math's correct on that one).
