The "uncanny valley" aspect is something I have experienced, but the big thing for me is the accumulation of three types of events.
(1) People trying to talk at the same time and taking several seconds to sort out who goes first.
(2) Glitches when everything freezes or even gets kicked out and brought back in, taking even longer to resolve.
(3) Wanting to say something and having to wait ages as people with less lag (I'm on the opposite side of the continent from everyone else) keep jumping in without a break.
Each instance of these raises my annoyance level. Dozens upon dozens of them even in a half-hour meeting can leave me totally exhausted from trying to tamp down the anger. By contrast, doing a 1:1 over VC isn't nearly so bad. Maybe an occasional bad moment, but not enough for fatigue to set in. I highly recommend that everyone do that comparison for themselves. The problems tend to increase more than linearly with number of participants, until there are enough that everyone accepts the need for strong moderation and two out of the three issues drop back to near zero.
