Well, I've played the game for about a total of 10 hours now, and I've unlocked every stage and every character except R.O.B. I think I can safely say that this is (at least so far) my favorite game in the Smash series. It is amazing how much content they've packed into this games, especially considering how it is on a portable console. Since I grew up playing on Game Boy Color it blows my mind that I can now play Smash on a portable console. I do have a minor gripe though, and it is more a hardware limitation and personal preference thing. I am used to using the c-stick on the Gamecube controller to do Smash attacks, so while it isn't the development teams fault that the 3DS doesn't have another control stick, it has still been a pain to adjust to doing Smash attacks with the stick+A.
