it takes 10 minutes of looking at the specs to know that it's not "superior" in every way. 
Quest 2 has wireless, much easier setup, better build quality and is slightly more reliable as a result. Not needing a PC to watch shit in VR is very, very cool.
Index has a much better OLED panel, a interesting controller scheme. The lighthouses are great when they work compared to Inside Out tracking of the Quest 2 but when it breaks it's the most frustrating thing ever. Quest 2 breaking is very simple to remedy 9 out of 10 times. Same shit with the controllers. The index's cable is also a failure point.
