> Once HA includes the Matter credential store in backups/restores, the experience will be the same
It was more a comparison of how quick and easy adding a Zigbee device is compared to adding a Matter device. Hit "Enable join" and the new device just shows up. For Matter it's either scanning a QR Code, waiting, hoping your phone is close enough for the initial bluetooth handshake - or hit "share" from an existing smart home platform (e.g. Apple/Google Home) which in my experience takes around 30s at a minimum.
FWIW, this is purely an HA issue, not a Matter one. Once HA includes the Matter credential store in backups/restores, the experience will be the same.
Out of curiosity, what is the reason you find yourself completely wiping and re-pairing all of your Z-Wave devices?
