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.
