Good FPS Controller?

I’ve purchased and tried about every single Mobile controller / joystick setup for mobile and I’m not happy with any of them. There is a lag or delay when you rotate the character around. I want something close to the way the Dead Trigger FPS controller works, very sensitive but not overly. You feel like it is responsive… does anyone know where I can get such a thing or purchase it? BTW I’m working in JS

Write it yourself?! This is the only way you will be able to get exactly what you want.
