It’s a good Chromium based OS native browser that has integration with your Entra ID account so all your bookmarks / history is automatically synced and users have seamless experience when switching devices. No longer seeing tickets like ″My bookmarks are gone after I reinstalled my PC″ is enough to consider Edge as your company main browser. And the fact that it is part of OS, you do not need to worry about install and patching.

I prefer Firefox, but from Chromium browsers Edge is really good, you cannot expect companies to suggest something like Vivaldi.
