Not sure. I bought the backbone, liked it, stopped exploring

I got mine on sale for about half that. The thing I really like about it is it plugs into the lightning port so it’s got a smaller delay in reaction. It feels good to use and reminds me of a much smaller switch/steam deck. I also have other controllers but this one is almost always in my backpack when I travel.

Looks like the Backbone

I’ll throw my hat in the ring
