Hi,
I am not too sure about the university of Stirling but big data technologies in Glasgow are absolutely brilliant. There is a high chance you will be with many Asian students mainly from India since most of them get funded.
The course involves every aspect of Artificial Intelligence. You will learn everything from cloud computing to artificial intelligence. On the other hand then one in Stirling uni is way more specific. The course there is more specific to a specific aspect of AI. Big data tech in GCU also offers industrial placements and engagement with employers right after you finish your degree. This is called KTP jobs. KTP jobs offer you do a Ph.D. and a full-time job at the same time.
Peter is the person responsible for the overall course in GCU. He is a great prof along with Mike (didn't want to mention surnames; for privacy issues).
Since you live in Glasgow i think it is worth of doing it here, instead of moving to Stirling. Ideally, I was you I would check the modules taught in both universities and compare. Modules and future opportunities from both of the unis are the main things you should focus on.
