You hit the nail right on the head!
I would like to add that all sorts of benchmark are somewhat useless unless the browsers' performance would vary by an order of magnitude.
The order in which the page gets rendered is far more important than the rendering speed.
A browser might be fast as hell but if he puts an image in a place where a link was before so that I keep clicking on images instead of links, well, this pretty much renders the fastest browser useless.
