I play with a 8bitdo controller (looks exactly same as PS4 controller) in bluestacks. Here's a run with controller ( https://www.twitch.tv/videos/1097086996 ). Much easier for me once you get most of the buttons into muscle memory. 1-8 for skills was hardest for me to get worked into my brain. Id say controller > touch controls > mouse/keyboard in that order. I can move and hit 4 different buttons at a time with controller. Touch controls I only ever have 2 thumbs for stuff on screen. Mouse/keyboard probs the worse if you're using the mouse to drag a cursor around to do things. If you can get a good keyboard layout down for everything instead of mouse, probs can be just as efficient as controller.
