Some Japanese controllers (or controllers targeting the Japan market) started using Gateron Kasumi Axis switches with a soft and linear feel.
The TIKITAKA R1A is one of the most customizable controllers that allows you to pick your own layout—as well as the keycap type.
The TIKITAKA JS1 is a nine button fightstick that is considered one of the heaviest fightsticks in all of history.
The VSLAB VSGEAR is proof that TIKITAKA's bestselling brand specializes in more than just leverless controllers.
The TIKITAKA M5 has one of the most unique button layouts, including 18 main buttons—some of which are ergonomically pill-shaped.
This is not the DuelPad Zen. It's the N17SP, and it has a split layout with 17 buttons—some of which are near the bottom.
If you don't need 16 or more buttons: the VSLAB VSNOVA N14 is a fine option with chamfered acrylic, customizable art, and cool LED.
The TIKITAKA M3 doesn't have 16 buttons. It has 17, and the 17th button is a rare fully sized start button on the top panel's upper left.
The star feature of the TIKITAKA E16 is definitely how you can customize its button layout completely and increase your winning chances.
