I have a g2 and the controllers really suck.
I mostly do casual gaming and sim racing so it's fine, but the headset easily looses track of the right controller when shouldering a rifle, and you completely lose track when the controllers go below your waist (unless it's a quick movement where the IMUs can estimate it).
Keep in mind this is solely about tracking volume, the quality is fine imo it only fucks up if I have my window shutters down halfway and they make a dot matrix that confuses the headset. Position tracking for the headset itself is very good, never noticed a problem there.
Batteries are a pain, I use 14500 bare lipo cells and a voltage dropper, I suppose you could use them without it but the power draw goes up with voltage so whatever regulator they have is a dumb one. Used briefly at 4.2v without burning anything anyway. 

Still beats sending your dick pics to zucc, at least Cortana compliments you before selling the pics to the biggest bidder.
Btw even if you go quest wait for the 128 model since it's gonna be the same price as the 64.
I would wait for deca gear to start rolling out tho, see what the fuss is about.
