Besides the usual poking Miku's face, not really. But the mini controller will have two big advantages. The Brook converter adds at least 1-2 frames of lag, which can only be adjusted for so much; it will always feel a bit off. The new mini controller also has the layout switch option from the old full size controllers for the first time, so it can be easily used with Future Tone. (Future Tone, while supporting manual remapping in game, ends up being unworkable using a converter because two of the main buttons end up being opposing sides of a d-pad, and the converter can't properly signal pressing both at once.)
