I just updated Safari and it does not work well on my end with Google Drive. Navigating through files and folders online takes forever. Had to get back to Chrome to work... so unfortunate!
I personnally find the new tab design awful. And I dislike the option that colors the safari interface depending on the displayed website. Apart from that, i am satisfied with the update (I haven't tested it extensively though).
While there are some small tweaks that would make it better, I like the update. The new compact view is great, and tab groups alone makes it a must-download if you use that feature elsewhere.
I’m really liking Safari 15, had been using it on my MBA running Monterey beta.
When it was released for Big Sur I pretty much immediately installed it on my iMac
