I think there is not really a point, unless you collect games. I've been there myself, decided to go with 2014.
It depends.
They keep changing some of the structure for the main "campaign". It was radically different between 2012 and 2013, from what I recall.
Other than that, sometimes there's different decks/cards/etc.
Additionally, if you're into the "puzzle" hands, which is one of the biggest draws of the games for me, they all have their own set of the puzzle hands.
If they're cheap enough, and you're a fan, grab em both.
If you can only buy one, probably go with 2014, but check the feature set to make sure you're on-board with how they've structured things.
