Dealing with the recent Nature study, for example, is it more neutral to throw in out of the blue that "Wikipedia is almost as accurate as Britannica" or would something along the lines of "Britannica remains more accurate than Wikipedia" be better?
Well, to stick to sourceable claims in the form of direct quotes, we could say: -- According to the journal _Nature_, "Wikipedia comes close to Britannica in terms of the accuracy of its science entries" [http://www.nature.com/news/2005/051212/full/438900a.html].
