But now that it's nothing but a slightly outdated Chromium clone, there's technically no reason to ever use it.
And because Microsoft keeps escalating their sleazy and desperate tactics to forcefully shove Edge against users' will, I'm making a point to never use it again. This brazen level of anti-competitive underhanded behavior with Edge reminds me that Microsoft is still as rotten as ever, so I'm also avoiding other Microsoft's products like VSCode, Azure, and I'm very worried about my dependence on Microsoft's GitHub.
Of course that doesn't mean I use it as my daily driver. It's lack of other features and my distrust of MS mean that I use Vivaldi as my daily driver. Which also happens to report the UA as being ms edge on bing.com so that Bing AI can be used without edge.
I use Firefox as my daily driver and dev browser, and chrome at the end to test compatibility.
I switched from Chrome to Edge a few months after Edge went chromium based because I could see the Microsoft developers started fixing the paper-cut design of Chromium's dev tools.
But I switched back when Edge kept disregarding my settings and filling my homepage/new-tab-page with junk each update. Sometimes it starts itself up after a background update and I can see even more junky sidebars, and icons shoved into the browser and I'm glad I stopped using it.
Newer versions of Chrome do a better job for me, so I recently switched to Chrome for daily usage, and Edge for testing.
One of our work computers runs it because a co-worker prefers Edge, so I have incidentally used it during tech support. It's fine, just not my cup of values-tea.
So I guess I use it.
