Hi k8snm,
To me the biggest advantage of the Tesla charger is that it has the Tesla connector. You don't have to deal with the adapter to J1772. When you press the button on the Tesla charger connector the charge port door opens automatically, no need to open it form the app or the screen. You cannot do that with another charger.
I have a 60amp circuit which I installed in case I ever decide to buy a Tesla Wall Charger. In the meantime I'm using a Gen 1 Mobile Charger that can charge at up to 40amps, which has been more than adequate. I tend to charge mostly at Superchargers as I have it free for the life on the S and X.
