Only been to Fontainebleau. To be honest, it didn't impress me. Felt too much like my high school. Also not down with the fact that Fontainebleau is literally a village on the edge of a forest.
From what I've heard and the videos I've seen, the Singapore campus is basically like a condo complex with some class rooms around it. Not sure I'd be too into that either.
This was one of the reasons that pushed me to Oxford.
