XCX > XBC 3D > XBC
Between being released in the west late, discontinued early, and Shulk in Smash Bros increasing the Xenoblade series's popularity I doubt either XCX or XBC 3D won't manage to pass the original. And although it may seem that 3D has the install base advantage since it's on the New 3DS which the Wii U has a bigger install base than it (For however long that may last.)
