I asked myself the same question and went with the ps5 version because i have a 4k monitor and my PC isn't beefy enough to power that thing. I played almost 100 hours with all my friends being on PC and had zero issues. I played all previous versions on PC and I don't want to go back to keyboard and mouse. Only reason for me to go with the of version would be the steam deck.
I have a disc version. Just bought and sold ff16 with only 5€ lost
