Play how you like, my friend.
I actually use both. I'm on a Steam Deck and prefer being docked and using a mouse and keyboard for shooters, but... I did learn the gyro controller for when I'm handheld, and it's not too bad! The game doesn't have a built in shooting range, but Haz 1 (the lowest difficulty) served that purpose for me pretty well when learning the controller aiming.
Have fun, and rock and stone!
