I wish everyone agreed on that.

gpsd handles a large number of GPS receivers, NTPsec not so much.
gpsd gives you tools to configure, manage, and monitor the GPS.
IMHO, gpsd does a better job of validating the PPS.
NTPsec can't handle just PPS, it needs another source to tell what
second the PPS applies to. The rules for that are a bit unclear to me.
But, lot's of people prefer the NTPsec ppp driver, or the NTPsec gpsd
JSON driver.
