The main difference is that it is not controlled by a small group with a bad track record when it comes to doxxing and violation people's privacy and lacking integrity in their editing.

They won't be winning me over just yet... search is slow and clunky, they want me to create an account (huge disadvantage), and they don't even HAVE an article for Wikipedia. I'll keep an eye on it, but so far it just looks like a Wikipedia clone that hasn't had time to make a bad name for itself.
