I use to G2 on a 2080ti… switched from Oculus Rift S and did a lot of comparison back and forth before I settled on the G2. Now this is before Q2 and their recent improvements really took of so can’t say that I would make the same choice today.
Flew XP with the Rift S a lot and loved it there, but from what I understand XP does not support G2 controllers yet so you might check that and keep it in mind before making the jump to G2, then you would be kind of committed to MSFS.
But all in all I think the G2 is still the king of shapness but if its worth the extra coin and transition to other softerware / comitment to MSFS is ofc up to you.
If you know someone who owns it I would ask for a try before making the final call though.
