I use Safari periodically because it's a nice browser, but by default i use FF, simply because Safari can't provide me with anywhere near the shit i want in my browser.
Opera is fucking good, give that a blast. I rate that as the slickest browser i've used, but then i've never used Chrome because allowing Google to spy on me is not something i plan on doing. I would use Iron, a stripped down version of Chrome, with all the spying and monitoring crap removed, unfortunately I can't use it (only for PC) but have seen it and it's supposedly quicker than Opera. I'd have a blast on Opera and Iron if i was you. Maybe have a gander at Safari, but imagine, like yoof says, it'll be iTunestastic.
