The original 2 although the remake of 2 was fantastic as well. I didn't have the PS1 but did play a bit of Resident Evil 1 at a friends house and thought it looked incredible. But I did get to play 2 on the N64 and that game was one of my favorite games of that generation. Resident Evil 4 and 7 payed in VR are not too far off. Playing a full tipple A game in vr was an experience, that hasn't been topped since in vr.
