The post that was quoted here has been removedAt the very highest levels, Nc3 is played almost exclusively. Why is that? Because it offers white the best chance for lasting advantage.
However, below the highest levels, nearly everyone has great difficulty against the French. That's why you'll find players advocating equality for white on move three (as the author of this thread).
At the highest levels, 1...e6 is a distant third in popularity.
