I feel like Apple has done the same thing to Safari and web-based Apple stuff, just always banging my head when developing for Safari browsers especially in a production environment when everything counts.
1) Way better battery life. Until the other browsers give a damn about battery life I won’t even touch them!
2) Cross-device syncing. My passwords and my tabs are always available on both my iPhone and my MacBook. Everything is synced through iCloud. I go back and forth so often every day that I could not see myself using a different browser on my Mac.
