As I have a twin, in depth, view of both tools perhaps I can provide you with some useful hints :
First you are talking of two very different tools although finality is identical. GQ is a GIS Connector 100% based on server architecture while Articque MAP is a pure QlikView and/or Qlik Sense extension which requires NO external server at all as it is installed straight into extension sub-folder :
This is key point because differencation between both tools stems from this very fact :
Each time customet download GQ he downloads ( one need to be aware of this as server is always housed somewhere ! !) server bits and pieces while there is no such thing with Articque MAP which is fully integarted into QlikView/ Qlik Sense and the job is 100% done at the local customer.
By consequence you have many analysis features you can perform with Articque MAP you will not be able to perform with GQ, such as ( but not limited to..) :
Lines and polylines
Customizable color pallettes
Customizable pies/histograms with diffrent expression per stake
Ventilation according to sepcific expression, set analysis for each stake
Storytelling and Developers' HUB ( Mashup) 100% compatibility for Qlik Sense
Layesr group management etc...
I hope this helps
