I used it few months and it mostly worked just fine. I had few crashes but those were rare. The main drawback was that their developer console was somewhat buggy, so eventually I switched back to Chrome because I needed it. Also 1Password extension for Edge was buggy as well.

And, oh my god, how many times Google asked me to install Chrome. They are really annoying with those ads which never stop to appear. I suppose that for many users that might be the reason to switch to Chrome, to stop that insanity.
