I really like Safari on OS X. It's my go-to browser on my personal machine, and on my work machine, it's my "personal" browser (I'm typing this into safari). I use Chrome for my work stuff.

But maybe this is down to your tab preferences. I simply hate tabs. To me, they're the sign of a failed window manager. I don't feel it's the job of every application to reinvent the UX wheel and implement tab functions differently from every other application.

Maybe some day an operating system will support tabs natively?
