Balena NTP servers vs Google NTP

What are the advantages in using Balena’s NTP servers over using the Google NTP servers?

Hello,
Any ntp server should be fine.
Devices will use balena ones by default, but you can configure any other ntp server in the config.json file: use "ntpServers": "space separated list of ntp servers"
