The good clouds don't support L2, they use a centralized control plane instead of brittle EVPN, and they virtualize in the hypervisor instead of in the switches. People are being sold EVPN as "we have cloud at home" and it's not really true.
AWS/GCE/Azure's network implementations pre-date EVPN and are proprietary to their cloud. EVPN is for on-premise. You don't exactly have the opportunity to use their implementation unless you are on their cloud, so I am not sure comparing the merits of either is productive.
