How extensible do I want a web browser to be? I have 1password and adguard but otherwise I'm not that interested in loading stuff in that can read all my browsing (e.g. grammar.ly...I just learnt to write instead). There's enough spyware as it is.

Safari is pretty fast and very good on battery life. I like that it has the same bookmark store and accessible tabs across devices.

And there isn't a lot of alternative. Firefox is slow. Chrome is a memory and performance pig; I run it only if I happen to use a google service for some reason and don't let it save any state.
