The old one was a unique controller with quirks. I have both it and the fancy xbox controller and depending on which game I am playing I use one or the other. I much prefer the trackpad over a stick for camera controls for some reason and the two stage triggers are neat. The trackpad is also confortable to use, thumb just kinda goes there, which is great for doing pc things when not at a desk.

The new one desperately wants to be both a conventional controller and a steam controller and what you get is neither. The trackpads can no longer be used for more than a few minutes without destroying your thumb and the two analog sticks are so close together your thumbs touch if you move them both towards the center. It was also super telling that one of the selling points was that you could change the way it behaves on a per game basis. A feature that steam has had for a decade for all common controllers.

Just buy an xbox or playstation controller
