I run a G2, things to consider (not an extensive list, but just what I can think of at the moment):
1. G2 is outside in tracking, so you don't need external base station equipment
2. You will definately need a high spec graphics card to get anywhere need the G2's 4k capabilities of resolution (i'm running with Radeon RX 6900 XT and wouldn't be happy with anything less ie Radeon RX 6800 XT (my previous card) or Nvidia RTX 3080). And you'll need to tweek your systems settings to get maximum performance, if you have all this I can definately recommend the G2
3. Make sure your getting the v2 cable, the v1 was/is glitchy/didn't work with x570 motherboards (this is an AMD CPU board issue only, no problems with Intel CPU boards). I got a free cable upgrade from HP Support withing a few days. Cable is 6mm thick and quite stiff + G2 doesn't have a WiFi option
4. In dark conditions the G2's tracking can sometimes stutter, this is not a major problem but can sometimes happen
5. You can buy the G2 as a headset only version, just depends if you will play other games that use hand controllers (EDO doesn't use hand controllers)
6. G2's over ear headphones are really good sound quality, built in microphone works well
7. G2's head strap is easy to adjust and the face mask is very comfortable. Headset is relatively light weight
8. G2 has variable IPD adjustment, not stepped like the Quest 2
9. I've not had an issue with standard FOV. I did buy an aftermarket face mask, which brings your eyes closer to the lenses, but didn't like it and couldn't really see the difference
10. You can also get aftermarket myopia lens from "vroptition.com" that fit over the standard lenses. You can wear glasses with the headset but its not that comfortable and wouldn't recommend.
11. G2 build quality is good, and I've not had any problems with the unit
12. Don't pay too much I've seen G2 with 2x controllers on Amazon at just less than £500, now running at about £550. Keep watching for price drops.
