If I use Edge exclusively in screenshots, people assume it's not cross-browser, it's not cross-platform, Microsoft is out of touch with other developers, Microsoft's living in a bubble, etc.
If I use other browsers for screenshots, I get comments like this.
As @dangrossman replied, we all use whatever browser we want for day to day browsing.
As a professional web dev, I make a habit of cycling through the modern browsers because it's just a good practice. I was the annoying guy in my dev team (not Microsoft, a financial services company) in the early 2000's that tested everything in Firefox when everyone else just wanted to use IE6 all the time. I'm typing this in Edge now, last week was a Chrome week.
