> As someone who runs Zoom via the browser (they do deploy a dark pattern to discourage this behavior but there is no good reason to trust them) I find that Hangouts and Teams are both solid alternatives in terms of AV quality. Would be happy to see some actual data on this claim

Some anecdata, recently i had to switch from Teams to Zoom, with the same person, and the audio quality was drastically better on Zoom for both of us.
