Hi Jonald_fyookball,
I think there are a few but specifically the variable stake modifier was a smart change, shorter block time, and not using coinage to affect your liklihood of creating a block.  But the security enhancements are sort of the baseline of what everyone expects/needs from a coin.  The bigger benefit - and one I feel like not anyone can just "invent" - is the community they bring to the table.  They could drive adoption *fast*.  Time will tell, but their presale has already sold about 35% and they just started it this afternoon.
