I also have both, and also hugely prefer PC2. It really has a better VR experience IMO. And of course, driving games are perfect for VR, especially with a wheel. The sense of immersion is huge. The wheel I have is the Logitech
G29 + manual gear shift.
Assetto Corsa if fine, but you have to jump out of VR to do anything while PC2 you can do everything right in the helmet. On the other hand, I hear that AC is a slightly better online experience, so horses for courses here.
