I use Safari full-time and am pretty happy with it. Pinned tabs, the keyboard shortcuts, developer options, ghostery extension, I find everything pretty neat.
I would use it since it's the native browser but last I checked it didn't have any proper ad blockers due to apple shenanigans. I would consider swapping back if I could use ublock origin.
I use Adguard with Safari 13, which has a bit of a clunky startup but doesn't seem to affect performance once everything is running & does a decent enough job of blocking trackers/ads.
I'm a full time Safari user. I love the "Share" button built in which lets me easily AirDrop and iMessage tabs I want to share between devices or with friends. It also feels faster on my MacBook and uses way less RAM. I open Chrome tabs only occasionally if I need specific extensions (Metamask for crypto stuff), run into webapps that simply work better on Chrome (Shopify for example), or to use the dev tools.
Anyone else here feel the same?
