The Quest pro is geared towards business so its really not competing with this unit and its stand alone device that does not need a PC to operate. Instead this device is competing with the quest 2 which I believe is cheaper. The PSVR 2 does seem to have better optics from previews so the price is probably justified but its definitely not at a friendly mass market price.
Quest 2 is $400 currently.
PSVR2 has a better display (OLED instead of LCD, higher resolution).
Eye tracking (which is hard to compare, most PCVR headsets don't have eye tracking, and it generally costs an extra $300).
