I've just got a Quest 3 and found it a great alternative to the G2, I have found the edge-to-edge clarity adds to the immersion and I am able to get what looks and feels like G2 visuals to me.
The head tracking is miles better than the G2, I used to have the lights on full in the room and sometimes position in VR would jump around with the G2 when it lost tracking, Quest 3 I was flying and didn't realise my wife had turned the lights off and the headset didn't miss a beat.
I am also finding using the targeting pods easier with the quest 3 not sure why.
Overall happy with the change to the Quest 3, I had to play with all the settings to get the performance and visuals I am happy with, but that's what we sign up for with DCS VR.
Would recommend giving it a go if you are looking to change the G2, just buy a better head strap.
