Some people are better with controllers, some are better with keyboard. If you qualify with the latter, buy a keyboard. If you can only play while using GameCube controllers, and you can really wreak havoc with a GameCube controller, I'm not going to call it cheating when you somehow connect a GameCube controller to your Ps4. Just because you are using a setup that allows you to play to the full extent of your ability, does not mean you are cheating.
