pop'n music - DAO buttons vs. Samduck buttons
Dao is green on the left, Samduck is red on the right.
Major differences:
The button height is quite different. Samduck is lower and feels more comfortable.
Daos are a LOT louder.
And of course, the Samducks do not get stuck at all. Played for hours and hours, nothing wrong has ever happened yet.
The winner goes to Samduck!
