The HD rumble on the Switch works great. Never felt like the rumble was overly loud, and it rumbling along with the game felt great.
Have you tried the Trance Vibrator mode? You can put the joy-cons on your... body... and they'll vibrate to the music when you play with another controller.
It's an experience.
Now is the time to buy 100 pairs of joy cons to make my own faux rez infinite suit
