So far, Google is doing much better than Facebook, with far more users overall (Search, Google+, YouTube, Gmail and other services combined) and also a social network that's growing fast. Google is also way ahead in the algorithm and "artificial intelligence" department, and in the mobile advertising business.
Still, don't count out Facebook yet. It's still got the biggest social network, and its strategy of building or acquiring many new apps is the right one.
Facebook and Google are headed in opposite directions to arrive at the same destination. Whether either company can get there is anybody's guess.
