Safari’s fast, less crashy, highest privacy protections, and uses less memory per tab; I often have hundreds of tabs so that’s important. It also has the best inspector, much better than Firebug. Add in StopTheMadness and an adblocker (currently using Ghostery), and it’s pretty great.

Degoogled Chromium is useful for sites that don’t work in Safari, or as a sandbox I don’t mind crashing in development.

I’ve given up on Firefox, it’s too fat and bloated.
