For physical form-factor? The Xbox 360 controller was my defacto controller since it was released up until very recently. It was controller gaming to me. I just started using the Kong Pro 2 from Gullikit (primarily for the hall-effect joysticks) and it's been a reasonable approximation. Everything else just feels...off.

For use case? The Steam Deck/Controller is unparalleled with it's customization options. There is basically no limit to what it can cover. It's amazing.
