Others have said this too, but it's not a matter of whether or not Facebook has that feature, it's the difference in defaults. I've been on Facebook for years and don't even know where to look for the "Friend Lists" --- and I'm a fairly technical guy who has tweaked all his Facebook privacy settings. With Google+, the circles are core, not just some tack-on optional feature. The main way to share something on Google+ is by sharing it with circles. To put it another way, the default on Facebook is to share with all "friends". The default on Google+ is to share with nobody - but the list of options starts with circles, and ends with the public. (Google+ also lets you include individuals in the list, but you have to type their name or email address, so I suspect that feature is little-used.)
