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.
I use Safari too, but I know what it used to be. That's what saddens me. It's still convenient, but the bugs in Mobile Safari of late are just... unacceptable. Particularly there is a bug, acknowledged by many others now, over many iOS versions, where the zoom freaks out in Mobile Safari and the renderer just seems to give up or something. How is that regression even possible? Ah, man. Everything goes to crap after a while, huh.
I’ve taken to downvoting anyone who says this, not because in certain ways it’s not true, but because it’s just such a lazy comment that adds nothing to the conversation.
