Katha Pollitt's obituary of Christopher Hitchens is the best one I've seen yet.
As far as I'm concerned, Katha is a better writer than Hitchens. I admire clear writing that precisely expresses subtle thinking. With Hitchens, the bombastic writing was sometimes getting in the way of the ideas, or covering up the fact that he hadn't thought things through clearly. Stylistic flourishes can be awesome when they help get the author's point across, but otherwise they're just distractions, however amusing.
