I use Chromium on macOS for development and occasional browsing. Chrome Dev Tools is really in a league of their own. But my primary browser is Safari, because it performs much better during regular usage on my 2012 retina macBook Pro which only has a paltry 8GB RAM. On my mobile android device I use Firefox, since it allows you to install extensions. Running uBlock Origin makes mobile web a vastly superior experience. I also use Firefox on Ubuntu and Windows, since it has the least invasive defaults and it lets you easily sync content across devices. I think browsers are actually in a great state. People have lots of incredibly high quality options to chose from! Although I'll admit I'm a bit worried that there appears to be a bit of a Chrome monoculture growing.
