I can vouch for this. I haven’t really needed the background blur feature personally, but I’ve tried it and both myself, colleagues, and friends — pretty much everyone I’ve talked to that has used it — loathe Google Meet’s background blur, and prefer Zoom’s by far.

In my experience, it doesn’t completely cover the background most of the time, and if you move at all, as you point out, it can’t keep up.

Kind of funny to see Google engineering blogging about it when it feels extremely half baked.

This makes me sad, because in all other areas, I think Meet excels well beyond the competition.

EDIT: removed my general sentiment on Google
