Edge was, initially, Chrome but degoogled and it had (and still has) a lot of great UI innovations, like a vertical tab strip that's just right. Their wide use of hovering menus that can be pinned to become sidebars is honestly good stuff.

Of course, that's UI design, they are worse for privacy than Chrome, and the UI advantages begin to slip by the aggressive introduction of all the bloatware in the world. The browser's never quite been free of dark patterns either (new tab page's search field as one of the more glaring examples).
