I've had a valve index for a while. It's quite possibly the BMW of headsets. Comfortable to wear, excellent tracking, high refresh rate, excellent resolutions, decent FOV, and good sound. Comfort is reasonable, however to get a good focus (Sweet spot) for my head the headset isn't in the most comfortable position. God rays and blooming are visible but only if you look for it. Pixel structure is better than HTC.
Games like Beat Saber and HL:Alyx look incredible and don't take a monster GPU. I can run 144Hz for Beat Saber and run 120Hz for HL:Alyx with little in terms of reprojection. However other games aren't as well optimized. Jurassic Park Blue for example goes into constant re-projection even at 90Hz. Star Wars Vader Immortal is questionable at 90Hz. Job simulator is another questionable one in terms of 90Hz. The later one passes with little on reprojection, but it's close to the 11.1 ms frame time limit constantly.

That said, knuckles individual finger control isn't always correct. A wrap (finger roll) of your fingers USUALLY fixes the issue. I think valve should stick finger molds (ridges) to help with placement of fingers.
Long term reliability is also an issue. There's problems with the headset data cord wearing out, and the base tracking stations malfunctioning. They are basically high speed spinning mirrors. There's also a problem with thumb stick drift over time.
It does come with a year warranty on parts, but at the end of the year, be prepared to dish out for repairs. Hopefully Valve offers a replacement cable soon. The other items are more "stomach-able", but not cheap for replacements. I think hand controllers are something absurd like $280. Headset $500. Light house 2.0 (Tracking stations) are $150 EACH.
Be prepared to buy extra face mask. If you have a family, get one for each of them. They do stink after a time.
So its kind of like owning a BMW. It's a darn nice experience, but it will bend you over when it breaks.
