Didn't realise this thread was still ongoing.
I have had the G2 for just over a couple of weeks now and it was mostly plug and play, as soon as I connected it Windows and Steam started downloading the relevant stuff. Set SteamVR's resolution to 50% as suggested by other G2 users and haven't noticed any issues with the small games I've tried so far. Tracking has not been a problem too, I heard the controllers is affected by weird lighting so I made sure no unneeded lights were on and to close the curtains since during the day sunlight shines directly in. Compared to the Quest 2 it's definitely a step up in resolution, I got the prescription lens mod too and everything looks great. I grabbed a pack of 1.5v Li rechargeable batteries too which works fine with the controllers no issue.
Don't get me wrong the Quest 2 is a great starter set, and the controllers definitely is a step up from the G2's, but I really wanted something with more resolution and I've been trying to avoid Meta services for a good few years.
Now the main issue I have now is... my lack of stamina when playing
