Well, its user interface is cleaner and better organized than say, Vivaldi's. It's strictly a matter of personal taste. It's fairly stable but to be honest, Microsoft Edge and Vivaldi have never crashed on here while Opera has done so twice.
Some little messes recently: A glitch in the UI resulted in an annoying message with a bizarre workaround until that was fixed soon after. Also, a recent browser update messed up my extensions but another update followed very soon after also. As long as there's a quick recovery of the browser, it's OK, things happen.
Right now, it's fast, neat and clean. I really like it. But Edge is a little more stable. Hmm, hope I don't eat my words down the road.
