Unfortunately, they'll be removing the webRequest API [1] which was the only reason I would have wanted to use it. This will happen probably whenever Google deprecates Manifest v2 and Manifest v3 becomes the only interface for extensions, which will stop uBlock Origin from working.
Other than that, when I tried Edge it didn't work perfectly on every site. But, it will be nice to have another non-Google browser to choose from.
This source (2020) also claims that global Firefox use is about 4% while Edge is under 3%, contradicting the claim (even including non-MacOS devices): https://gs.statcounter.com/
Yeah, I hate to throw anecdata around, but I didn't even know it existed for the Mac. Is Edge 'built in' to some other product, so it scores points on a technicality?
Edge? As a Mac user for many years, I can't recall any time I might have even considered using Edge for anything. I guess they ported it to Mac not too long ago, but who cares?
