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.
But Google Meet is pretty good otherwise. Zoom is good too. All others I have used have been quite annoying to use.
Wordpress is a pretty bad example though, surely you’d just CDN cache the pages!
i'd like to see a comparison against a firecracker vm and a docker container
Seriously, Hetzner provides so much move value per dollar, sometimes I fear that one day they will find out and just jack up the prices to match the rest.
