Until just recently, I used exclusively default controls, first with the Gamepad and now with the Pro Controller. Recently, however, I've been using tilt stick for certain characters.
I've always used tap jump as my primary jump, so losing that would be a big adjustment. I've gotten used to the position of all the other buttons (sans X & Y, which I don't touch) and their functions (to the point where I have to swap the shield/grab button on GC), so I don't bother changing any of them. I use the right stick almost any time I need to do a directional aerial and thus tend toward double-sticking. This is why I've started using tilt stick for some characters (especially
), because double-stick short-hop up-air is challenging with right stick set to smash (which I used because my main at the time,
, gets a lot of mileage off F-Smash, which would be more difficult w/o smash stick).
Maybe there was something useful in that ramble, IDK.
