Maximum best immersion so far I've had for VRChat has been Oculus Quest with ALVR wireless pcvr, 4 Index base stations and 3 Vive trackers all in a big room. I've had Vive Pro wireless and Index to compare to. 

In comparison Vive Pro wireless is very bulky to wear while having comparable visuals, audio and mic to Quest but with less latency. Index on the other hand has mostly superior visuals with a bit washed out colors and gray blacks but in much higher resolution and field of view. The audio and microphone on the Index are much superior too. However the Index is wired and that really gets in the way if you're actually active in your big room walking, dancing and rolling about on the floor. The Index Controllers are kind of mediocre too, while it is nice to wave your fingers you are only like 90% sure which expression you're making while with Touch I feel a comfy 99% confidence level. A lot of avatars also have their hands break when using Index and doing basic stuff like victory gesture gets a bit janky.

The downsides of Quest are mediocre graphics, microphone and headphones quality, the 60-70ms input lag you get from the wireless ALVR setup and having to calibrate your shit every time you get online. Calibration is lost if all of your trackers leave the play area so that's a bit annoying but manageable. Quest allows 3rd party headphones to be plugged into the headset and you could get a 3rd party mic too so those issues could be remedied by more effort in your setup. Battery is about 2 hours for the headset but you can use a power bank just like Vive Pro wireless does.

Wireless is really a 2nd gen feature and the future. People who swear by roof cabling are delusional or have small rooms, I've tried that and it's a band aid at best and doesn't really work in a big room.

For absolute best experience get 2 sets of everything so you don't have to lug around extra power banks.
