I just don't understand it. It doesn't have conventional analog triggers, yes it may be more comfortable than the joycons but it offers less features to cost compared to buying another pair of joycons. 4 players vs 3, using MARIO kart as an example. It's less Mobile than having the slimmer joycons on the go.
No hate toward the pro controller, Just weighing pros and (joy)cons here (haha)
