For me Safari works good enough, so I don't have many reasons to switch. Chrome development tools are marginally better, so it's still installed and I use it for some heavy JavaScript development, but outside of this I prefer Safari.

Funny enough, I had to use Windows 10 for a short time, and Edge was actually not that bad. I remember IE being the terrible product and everyone used some other browser. Now Edge is usable and there's no much reason to install Chrome there as well.
