As fighting games have gotten more modernized, 14 button controllers became more useful. They’re essentially 12 button controllers with two extra buttons.
The HauteBox One is a wireless split-layout controller with lever and leverless modules that are interchangeable.
The Haute42 W-P1 is a sloped controller with an optional wireless connection, and it is available in white as well.
The Alpenmeister TE's Hall effect switches allow you to adjust the button sensitivity, and there are also D-pad buttons near the aux buttons.
The 8BitDo Arcade Controller Pro adds a left pinky button and brings the right thumb button closer to the jump button.
The HauteBox Zero is a 14 button ergonomic controller that utilizes Wind Engine switches and is made of metal.
The Bishop|Select Opal is a more affordable version of the Maestro, and it's ergonomic—but not too ergonomic in a way that's unfamiliar.
The X-Move is a sequel to Haute42's modular controller that was nominated for an Evo award, and you can move some of its modules sideways.
The PWS R14 is also available in layouts that represent the following Japanese pro players: Gachikun and Shuto.
