Q2 PCVR is 90hz with near-zero latency (16ms)
with wireless 
. 72hz? You're just straight-up lying now, homie. If you really want to big-dick around over a 16ms
full wireless PCVR experience then, lol, you do you.
Index is more comfortable - debatable, as Oculus has options here.
Index has a real IPD slider - Okay. I've not missed one, personally. Some people might.
Index sweetspot is much bigger - Okay. I've not really noticed any issue on Q2.
Screen quality - Oops! I hit a nerve. Someone's mad that the Index's display is inferior (by a long shot, mind you). I don't give a crap what the tech is - if it works better, it works better. And the Q2 absolutely dismantles all other headsets here aside from the G2.
Setup - HUGE advantage for the Q2. Imagine trying to play VR in other rooms in your house with the Index. Hilarity ensues. It may not be a big deal for tryhards, but it matters to a common consumer who, you know, doesn't sit in the same room at all times. I can take this to play at a friend's house within 10 seconds, shift to the living room wirelessly, and anywhere in between. Want to play outside or in a big warehouse for a 1:1 experience with that Index?
Re: Desperate -

So salty. The Q2 is superior to both the common consumer (price vs. performance) and a lot of enthusiasts who are willing to admit that their $1k investment has been bettered in many ways, particularly those that count, by a glorified mobile device. Again, having both, my Index is covered in dust and no one who comes over even cares to use it. It's a fine headset, but needlessly expensive for what it is, particularly since the Q2 has two years of tech advancement over the Index. I mean, lol, the Q2 has
actual hand tracking. Without controllers.
