Opera feels smoother and faster than the latest Safari version. More customizable than the previous version and with more features than Safari. I lie the panels, the Print botton, and the search in page box. You are able to import all the bookmarks from the major browsers which is very convenient and useful. UI is cool, you don't need extra software to customize it. I think is a great improvement and you should try it and compare it to the other browsers. Until now I have been using Safari & Opera but with this new version I think I am staying with Opera.
