Firefox most versatile, best extensions, and respects my privacy. May not be fastest if your counting nano seconds. I love how I can scroll through my tabs with mouse wheel and expose bottom navigation bar and context menus and bookmark bar.
Tried them all aside from Safari. Edge and Firefox for me. But I go Firefox because they are important for what they've done and I like MS but want to support the big players as little as possible because the big players typically harm the system overall in one way or another, and the whole *poly thing comes into play.
I'd use Min as a daily driver if it supported Widevine streaming for Hulu, Netflix. That's the biggest barrier of entry for browsers to me. Only the major players have DRM support and I like my X-Files.
