Lower latency
Comes with the system (greater likelihood of asymmetric gameplay integration)
Doesn't cost $200 extra on top of a $400 console
Doesn't require a router or connection
Has all buttons necessary available.
More versatility
Addition to whoever wants it, not a mandatory purchase for something you may not even want.
Ideally, you already have a vita. You know, it's a gaming system. The analogy would be a 3ds giving you remote play (HA). Also, ultimate bundles.
It has many ways to connect to the ps4. And yes, the wiiU needs to establish a connection, the downfall is that said connectivity sucks balls.

Who's moving goalposts? That Diablo comment was only one part of my post.
Sure.
Welp lets just hope that no game ever needs to use these buttons together.
User remapping would be possible if sony digs into it. Remapping keys seems pretty simple. Vita has a back touchpad which can be used in 4 zones to get the L2,R2, L3,R3 and a front touchscreen to emulate the ds4 touchpad. If they want, they can.
