Index pros over Q2:
Refresh rate is much higher
Tracking quality is much better
Native FBT support
Finger tracking on the controllers (meh desu)
FOV is wider
Comfort
Native PC support
Doesn't run out of battery
Not being zucced

The only thing Q2 has over Index is resolution (which is reduced when you link to PC because bandwidth), wireless option which is only useful for short play sessions and some zucc exclusives
