There wasn't even something wrong with Edge when it started. It was basically Chrome, but preinstalled. But now they had to fill it with bloat and spyware...
The rendering engine was nicer than ie, but they built a queue between the UI and the browser engine, so navigation including the stop button didn't interrupt the work in progress until it polled the queue, which could be seconds later when it had gotten stuck (as browsers do), and then it would go ahead and do the many actions you had queued up.
Reskinned Chrome is less bad, I guess.
