Firefox all the way. In strict privacy mode with enhanced privacy settings toggled under about:config. Add to that the best content filter out there (Raymond Hill's uBlock Origins) and you're gold.
I do use Edge 3-5 times a month for those poorly programmed sites that totally break when any kind of filtering is enabled, but that's it.
If, from it's inception, Microsoft just offered Edge as an alternate browser, didn't try to push or trick people into using it, and instead, spent that advertisement money on actually making a better browser, more people would probably be using it today.
Manufacturers still need to realize that the absolute worst way to get someone to use their product is to try and force or trick them into doing it.
