g2 HMD is only the preferred option if you can't get an index. I'm going to use it to upgrade from the original vive headset but I will keep my lighthouses up and my tracking pucks for full body in VRChat. 
Breaking up the perfect compatibility of the index hmd + index controllers + lighthouses + htc trackers for the marginal improvement of picture quality of the g2 is absolutely not worth it. I would totally go for the index hmd if it was available in my region.
