It is quite normal that they are off by 200 ms and jittering. That is characteristic for that method. In gpsd it is only used to set the clock to the nearest second, so it is not important.
When you want to use gpsd and have an internet connection, the ideal config is to have the two gpsd clocks and three external references from internet. ntpd will have no problem to choose a correct initial time and will keep locking on the pps clock (second clock of gpsd) as long as the GPS receiver is locked to the satellites.
