Safari is noticeably faster and smoother than Chrome on OSX. I'd prefer Chrome because it has a lot of things that have to be shoehorned into Safari with addons, but I'll use Safari until Chrome gets it all together.
Of the three, Firefox has the worst font rendering. Text on it is noticeably blurrier than on Safari or Chrome. Safari and Chrome look about the same but Safari has slightly more contrast to the text.
