I've used both, and they has nothing in common IMO.
The 2013 16x19 blade has a sweet flex, that's true, but it has much power and pop than the nBlade. My old nBlade (I still keep one of this jewell in my wardrobe) is one of the sweetest racket I've ever used, if isn't the most. And the control response has nothing in common with the new blade.
