rGeo vs. gstat

Dear list members



I'm very new to R but a little informed about geostatistics. 

As I was looking for possibilities of geostatistical analysis in R I encountered at least two very interesting packages: 



Rgeo and gstat



And of course I'm wondering now about the one which fits better my needs which are the comparison of spatial data (insect parasitism rates) for different fields in which we collected data. 



Best wishes
