Yeah they’re not even comparable. Multi monitor setups are great for sim rigs where your head will stay relatively static.
I mean the last head set I put on was a virtuaboy in a Toys 'R Us in the 90's. I'm definitely completly out of the loop, but also, I primarily play top down games, not things from a first person perspective. Maybe this colors my perspective too?
I will say for the price my Quest 2 has been very impressive. I don’t currently have a computer powerful enough where I can do PCVR with it, but even standalone is pretty stunning. I think they’re around $300, and sometimes less if you can shop at Costco.
