How can I disagree? Since way back in 1998, with civil simulators, I've always flown in 2D. Then, in DCS, I started using the Trackir and I already saw a big difference, but there was still a "perceptual" limitation.
But when I finally switched to VR last year, the leap was epochal: nothing compares in terms of immersion, immensely distant from the Trackir and light years from the 2D monitor.
And now that I've also been able to get hold of the Reverb G2 with the Oasis drivers, my experience has improved enormously, both in performance and quality compared to the Quest2 I initially had.
