this question is perhaps better posed to the gpsd mailing list,
http://gpsd.berlios.de
(which is worth checking out anyway if you are thinking of NMEA parsing)
GGA is definitely the more standard - I've never heard of GGK.
RMC,GLL are worth a look as well.
My guess is that ultimately it depends on your GPS.
do a web search for "nmeafaq.txt" It might help.
