You look at the page contents constantly, at tab names often, at the bookmarks toolbar sometimes, at the URL occasionally, and you almost never look at the page title. In 3.6 these are arranged in order radiating from the center.
8.0 completely breaks the flow by sticking the address bar below the tabs. WHY. Also, where's my status bar, with all of my plugin status icons that I use constantly?
4.0+ is still broken, so I'm still going to use 3.6. Simple as that.
