In my own experience, Chromium browser (which is the base for Google Chrome) works much better (faster) than Firefox on my Pinebook Pro (ARM, Linux).

But I think the author is using Chrome under emulation, so bad performance is expected.

Correct, I didn't grab the ARM Chromium build, only Chrome. If you want to avoid using Edge then Chromium or Firefox is the way to go.

Given edge is just a chromium wrapper, why avoid it? Just ecosystem issues? (Password managers, etc?)

I don't avoid it, but some people do because it's a Microsoft product, as is tradition.
