I’m very familiar with Safari address bar issues, where sometimes Safari just fails to navigate to a URL and you get an audible bell, or just general weirdness when you type too fast, and can say I have yet to experience these same issues in 14. I’m sure there are other problems but Safari has generally improved with every release.
RE: extensions, I run Adguard for Safari and that’s pretty much it; it’s free and it catches most ads. Safari also has built in tracker blocking now, which is nice to have but more or less ignorable.
The nice thing about having Safari be your main browser is that you can reserve Chrome for development, and having a vanilla Chrome browser where content scripts don’t haphazardly log things to the console or block requests is really nice.
