I have found Microsoft Edge to be well suited for most work-related scenarios that occur during a typical workday. I am able to access benefit vendor websites and HCM resources. Shared files in Office 365 are accessible through Microsoft Edge. I view webinars in Microsoft Edge because it is relatively easy to group webinar handouts into tab groups.
I use Edge daily - all day. I typically have 2 Edges open on two different screens as well. While Edge and Chrome are both built on the Chromium platform, Edge completely beas out Chrome regarding security, usability, and functionality.
Microsoft Edge is bundled with both of my laptops, but I have no reason to get rid of either. Opera, when I used it, was a bit clunky, and frankly a little bare-bones for my liking. Firefox is an equal for Microsoft Edge, but has an issue with stability on my personal laptop. After working around those issues for a couple of years, I wound up moving to Microsoft Edge, and have had no performance or connection issues since.
