Google Meets is not as good as Zoom for our major use case: multiple couples of family or friends, each with a laptop.

If you try this with Google, at least when we used it, it didn't have multi-display: You could only see the "main group" talking, which might be someone laughing or ruffling a bag of crisps. Furthermore, the sound quality was straight up worse than Zoom, borderline inaudible with the same equipment Zoom gets.
