whatever controller is closest and convenient for me when i happen to sit down, or whichever one is charged lol.
I usually gravitate towards a wired xbox controller because its the one i have jurisdiction over in the household.
Strongly recommend a wireless mouse/kb with one of those couch cushions that is desk shaped. very good for playing some of the less controller-friendly games. I got a half-keyboard with a joystick on the thumbrest that i havent used yet.
yeah. you just kinda wiggle with the music. more complex dance moves are practiced.
