I have HotCat enabled in monobook and it's very superior compared to Wikia. It's easy to see from the summary what categories have been entered, and it doesn't randomly move categories from the place where they are in the article, nor duplicates them. Also you can filter which categories you don't want to allow people to use (for example, those added through templates)
