Does the Gamepad make a big difference in TW101 and Wind Waker HD?

I don't have Wind Waker HD, but for Wonderful 101 there isn't really anything that essential about the Wii U gamepad that is game changing, in fact they even give you the option for off tv gaming with it.

This is precisely the "big difference" I feel the gamepad brings. Off-TV gaming is a huge, huge thing IMO.
