The German Wikipedia is large and sees a lot of activity. Articles about topics relating mostly to Germany, Austria or Switzerland are usually better than the English ones. Other articles are often somewhat biased towards a readership from those country, which is actually helpful if you live there.
Lower English language fluency in the general population, compared to the Netherlands or Scandinavia, supports this of course. But also the fact that German remains a scholarly language to this day (in the humanities but also in some branches of engineering).
