Each controller style has its pros and cons. The style you pick will depend on your setup, budget, and what kind of games you play. Wireless controllers are easier to move around. You don't have to worry about getting tangled up in cables, you don't have to take up a USB port, and you can sit farther away from the console. Most wireless controllers use Bluetooth, which means they can connect to devices like iPhones, iPads, and Androids too. They're also more likely to have features like motion controls and remappable buttons. But wired controllers never need to be charged, since they take power directly from the Switch. They'll also have less input lag, and there's no risk of the Bluetooth connection glitching out — this makes them a necessity for competitive fighting games. And although they lack some features, they tend to be much more affordable than wireless controllers.
