There are many alternative controllers available from third-party manufacturers for the Nintendo Switch. In fact, there are so many of them that you can easily get confused over the wide range. If you're looking to buy a new controller, Howtogeek.com has recommended the best options.
Advantages: price, Bluetooth and USB, relatively rich functions
Cons: no magnet, need to reconnect to Switch when changing devices
8Bitdo Ultimate C is the winner in the “cheap and cheerful” category. It supports both Bluetooth and USB connectivity, both of which provide smooth and responsive control. The controller features a textured grip that feels comfortable in the hand, six-axis motion control, a non-linear digital trigger, and dual shutter buttons. Not bad by the standards of the modest price. However, if you suddenly want to connect the controller to another device, you'll have to re-pair it to the Switch next time.
Pros: Full-sized handheld controller, turbo mode and customizable triggers
Cons: limited color selection
The Split Pad Compact is a comfortable choice for those who frequently use the Switch in portable mode. Plus, unlike the Split Pad Pro, it sticks to the slim shape of the original joycons, making the device more compact. This accessory is officially licensed by Nintendo and supports customizable triggers, as well as a turbo mode that increases the speed of button presses. Despite its size, the Split Pad Compact is a surprisingly lightweight controller that fits comfortably in your hand thanks to its textured grip.
Pros: Magnetic sticks and triggers, customizable rear buttons, great battery life
Disadvantage: high price
The Gulikit KK3 Max is the perfect controller for the Switch that can also be used on PC. With three modes and two vibration powers, a six-axis gyroscope, and four removable and customizable buttons on the back, the KK3 Max can be customized to suit any game. Additionally, the stick's sensitivity can be changed in the app, and Smarttrigger technology lets you switch between digital and analog modes for triggering.
The magnetic stick ensures resistance to drift, the main problem plaguing all official Nintendo controllers. Additionally, the KK3 Max can operate without recharging for 28 hours. This device fully justifies its premium price.
