We should make a Q2 faq/pastebin given the number of questions. Anyway, as someone who owns both:

Index is noticeably more comfortable, Q2 becomes fairly comfortable with a third party strap. I like the VRCover one, the elite headstrap is hot garbage.

Index has considerably better audio, but it's non-isolating so if you're not living alone you might not want to use it. Quest 2 really needs IEMs.

Q2's display and optics generally wins against the Index, it's clearer and higher resolution, god rays are an issue but much less so than with Index. Colours are a bit lackluster by comparison though, you can fix this a bit with some tweaks but the contrast just isn't as good.

Refresh rate, Q2 is getting there with 120Hz coming soon (technically already here, but not yet for link/PC). Index goes up to 144Hz, personally I'm not very sensitive to 120vs144, but 90 to 120 is a big step up.

Field of view of the Index beats the quest, ~100 vs 130. But note this is not horizontal FOV but combined. The Index's horizontal FOV is a bit better than the Q2's, but it's vertical FOV is considerably better. In my opinion this means that the FOV difference is less significant than you'd expect, you'll catch the top of your anime tittes, but you don't gain that much peripheral vision.

Q2 has awful IPD adjustment.

Tracking is better for the Index, plus it has the option of FBT. The difference in tracking quality used to be huge, but Oculus' inside-out software is some sort of witchcraft. It's now marginally better so long as your hands are broadly in front of you, but not hugely. If you want your hands behind your back etc. it won't work well.

Wireless is a point to the Q2. It has inbuilt wireless capabilities, currently you need to buy virtual desktop for this, but it will be in the base software soon. Nice for being in bed.

Standalone functionality is nice, it's easy to sideload any apk you want so you don't really need to buy anything.

I think that's it.
