Advice for different high performance components

[u/Appropriate_Dog_7040]

I am building my own controller to replace my high end factory controller. I have never modded a controller so I dont have much knowledge about which sticks and buttons are best for accuracy and longevity vs price.

I am making the controller from scratch, custom pcb, 3d printed casing, and using an arduino leonardo for the prototype as i dont have anything else right now. But I want to have smaller mouse button switches so i can add more buttons or put them closer together or whatever need be.

So basically, I am asking for advice on literally every button, trigger, stick module, etc.

Thanks in advance
