I've been using it for a while. Overall, it feels significantly faster than any Chromium-based browser I've used. Chrome, Brave, etc. are simply no longer good enough.
That being said, I'm considering switching to Quantum. Edge breaks the 1Password plugin[1] and Microsoft is closing the bugs "as designed" or they have lost all traction. Breaking a password manager relegates the entire browser to non-starter, it doesn't matter at all how good your other features are.
