What you want is Stratum-1.
The only place for us to get that it by using time.nist.gov as your NTP server address.
The primary advantage of using that URL is because all the others have various response times and even downtimes. time.nist.gov is a 'smart URL' which finds you the quickest and most accurate time from the National Bureau of Standards Master Clock. This is the same clock the Navy uses.
It is an easy change in Raspbian and most flavors of Ubuntu.
Rather than repeat what has already been written here about this, please allow me to refer you to a Q&A in this Stack Exchange that explains how to set it up:
This article also mentions how to set your Windows computers to use the same Stratum-1 NTP source.
