I can tell you from experience, that with the Adafruit hat, and the default sentences, 9600 baud is not fast enough. Some periodic sentences (period > few seconds) will push a cycle past one (1) second. Even when used with PPS, eventually it will eventually be marked as a false ticker.
When this was my main NTP server on a Pi, I turned off all the sentences, except the ones I wanted, to avoid this issue.
