Safari has a few things not going for it: 1) ad blocking options are really inferior to chrome (for now) or firefox so a lot of what you gain in speediness gets taken away by some of the garbage that modern websites spit back at you. 2) The dev tools are confusing now. They have good ones but they need to redesign some of the UI on it. 3) There's not a good way to containerize things which means you end up having to open private windows when trying to login to services with different users.
