I use Edge at $JOB (because we live in Windows land and Edge integrates better with Windows stuff) and Firefox at home. I also used Chrome in the past.

Whereas I agree Firefox used to be way better than IE when I first used it, I can't really perceive any notable difference on performance for those 3 browsers.

There are some minor diffs (edge has veritcal tabs and allows login in with your AD account), but that's it.
