I found Edge to be useful for Enterprise/Business environment. My previous job uses Office 365 E3 (and their email server) and entrenched with them for various external services such as MS Authenticator for SSO. It is easier use Edge for SSO since I don't need to keep typing out the complex password for my job. Whenever the password prompt show up in Edge, I click my work email account and it automatically log me in. I have one desktop and one laptop for remote work, it simpler with SharePoint/OneDrive to keep my work data synced between both computer. Edge have their uses in Enterprise/Business setting.

For personal use, I rarely use Edge. I only uses them for websites that have an issue with my Firefox with uBO and strict CORS. I avoid Chrome like it is a plague.
