I think the complaints with the Quest 2 really boil down to these two points
>Muh Faceberg I hate the antichrist
and
>the hardware is too weak
Otherwise I think it's pretty much the ideal format moving forward - a headset with dedicated processing power for untethered hassle-free play-anywhere capabilities, and the ability to tether (wired or wirelessly) and take advantage of PCVR.
If the Quest 2 was developed by Valve and cost $1000-1500 with much beefier hardware, everyone would probably be singing it's praises as the best VR headset ever developed and a cutting edge pioneering headset.
In any event, as it is now, I think it's a pretty good gateway into VR and aside from muh faceberg schizos history will look favorably on it (if VR doesn't end up as a fad like it did in the Virtuaboy era)
