The index is also not as good as the quest 2. Although if a valve index full kit were selling for 233.3 dollars (1/3 of 700) that is honestly worth it solely for the basestations to use with full body tracking. Basestations tend to sell for 300 usd a pair.
I'm not seeing any index full kits selling for that cheap though, at a minimum 550 for the full kit.
