Those "objective comparisons" then probably compared the rendering engines or some other micro benchmarks. My main problem was the GUI, not the rendering (though the latter probably played its part in slowing the GUI down). Opening/closing/moving tabs was sluggish. Just opening Firefox with my ~20 tabs open would take many times as long as opening Chrome with the same number of tabs. You didn't need a stopwatch to see the difference.
