I haven't used Chrome enough to say because if you increase the text size on Chrome to where I like it then the text spills over the right side of the window (at least on 13.3-inch Macbooks) with the result that one has to scroll back and forth horizontally for every line of text. I admit that my preference for large text is unusual though.

Safari was unresponsive (spinning beach ball) even more of the time than FF has been.
