Compare two point datasets

I have two point datasets of tobacco retailers - the gold standard is based on actual tobacco license files, the other based on the types of stores that sell tobacco (conv store, grocery store etc). 

I want to compare the two datasets - spatially, to understand how different they are.  Neither dataset has attributes in common (one has the name, the other the type) and I don't really care about the attributes.  Essentially, what I want to know: is the dataset with store type (which I can get nationally) a good proxy for the dataset based on license files (which isn't available nationally, but I can get it for a few states to test).

Any suggestions on comparing these datasets?  Anything I've come across is really getting at a relationship between their attributes rather than their location.
