Actually, I think the 'inner' one is easier than the 'outer' one. This is because: 1. The 'inner' is longer than the 'outer', but the length of the crazy part(starts with 1:45) is the same. This make the 'inner' less rely on the crazy part. 2. (only for the game that use button) The change of red and blue of the 'inner' is greater(still, not compound). This made the finger can change more quickly and it will be faster.
