That’s why I’d like to know which school is considered better for job prospects, knowledge, environment, etc in Scotland?

Statistically, for job and wage prospects the hierarchy is typically:

University of Glasgow > Glasgow Caledonian University > University of Strathclyde

Artificial Intelligence is a new Msc at University of Strathclyde, so it'll be difficult to get any metrics or opinions on how useful or what the job prospects for such a degree is while the ones at UoG have been around far longer, have higher entry requirements and last I checked near 100% student satisfaction.

If you want to play it safe, I'd go with UoG if you have the option but Strathclyde is by no means a bad option.
