One concrete thing that is better about the Tesla connector is that there are no moving parts that user needs to manipulate.
Tesla/NACs connector is just stick it in and it works... the car holds onto it until it is done or you tell it to let go.
I don't think I've ever seen a public J1772 connector that had a functional spring in the little thumbpress/lock/turn on thing which means if you don't know you need to stick a key or pen cap, or squeeze really hard to pry the little fucking plastic tab up to the lock position, it just won't work.
