I like some of the tricks Chrome has like automatic 'research image' context menu, but most of that stuff can be replicated with simple FF addons.
What I HATE about Chrome with the fire of a thousand suns is its paternalistic, hide-all-the-options, mystery-meat organization. It thinks it knows better than the user, which is never the right answer. That said, Chromium on Linux is very clean and fast.
IE 9/10 are actually surprisingly solid. Haven't tried 11 yet.
