I have a gwatch 4 and the hardware is fine. The flaw is Google’s half-assed android fork WearOS, and then the layer of Samsung software that somehow makes it worse.
You could have infinite memory and processor in there and it wouldn’t solve the jank.
Honestly the 2nd analog stick I didn’t mind too much because the face-buttons made a decent D-pad for the tiny handful of shooters on the DC. The bigger flaw was the lack of 2nd shoulder-buttons.
Also that putting a screen into a controller has always been a solution looking for a problem. It was on the DC, it was on the Wii-U, and there’s a good reason they abandoned the idea to put a screen on the PS4 touchpad controller.
