My Meet calls always end up pixelated, where Zoom looks perfect. That’s basically the only thing I care about after the audio quality, I often cannot read someone’s screen when shared via Meet. Zoom also feels lower latency but I never checked if that’s the case.
You might be hitting QOS limitations where traffic from Google is bundled with YouTube et al and served at a lower priority ?
In my experience Zoom is always slightly better, but at a nitpicking level. I use meet day in day out, and fallback to whatever we have in hand if it's unworkable (pixelation would hit that line), and never saw zoom or Skype or discord being significantly better at these times.
Note sure if that’s because I’m not in the US.
