Even calling it "great" is an exaggeration. It can't support anywhere near the power delivery CCS 1 or 2 can, when 800v architecture cars are now commonplace.
It's sheer fantasy calling it better than CCS2. What should have happened is someone should have mandated CCS2 for the US.
It's not that Tesla's connector is better (CCS1 has the same communication/payment stuff Tesla's does), it's that the US used a installation grants and legal settlement to build out a bunch of charging infrastructure with no requirements for availability/reliability. So, shockingly, lots of charging stations went in and nobody gives a shit about maintaining them.
The only problem CCS1 has is the shitty mechanical design that can't handle heavy cables. It's a problem that could be worked around simply by installing a hanging arm that supports the cable or handle. But again, there's no incentive to fix it.
