Nothing on this page (or the nested "Switch to Safari" page from Apple) seems like a compelling enough reason to even consider switching to a new browser. It feels like it was written by nerds who care about tail-end optimization instead of actually marketing real, useful features to real people. Reminds me of a friend who used to try to get me to switch to Firefox because it had 8px more screen space for content compared to Chrome.
"Better rendering performance of animated content"?
Some sites literally just don't work when you visit them in Safari. I'm not gonna go through that just so gifs play a little smoother (?)
