This Wiki was the Combine OverWiki until 2012, the old administrators started hating Wikia's "improvements" (ads, new skin breaking things, etc) so they moved to combineoverwiki.net

You can see that many of the articles here are also on the other wiki (just cleaned up), so the difference is that they have a dedicated and well organized team of people editing constantly and far cleaner, more informative articles.
