Keyboard for anything not requiring or allowing diagonal movements.
Everything else gets my Qanba Q4, a great stick for under $200, has survived multiple Yolympics, Craps, and IGBYs. Comes w/ 9 Sanwa buttons. Also comes w/ stick restrictors, so can do 4-way, 8-way, and all-way (circular). Very sturdy, though the stick does auto-center a little too quickly for DK Jr, which might not be a bad thing.
