Cost of living is actually a decent shout. I didn't really consider that. The nicer parts of Glasgow probably represent much better value than areas of similar quality in Edinburgh. It depends how much you treasure having a city on your doorstep.
In my opinion, areas like Millingavie, Bearsden, Newton Mearns are proper suburbs and aren't well connected to the city without a car - compared to say the Meadows, Morningside, Bruntsfield in Edinburgh which are actually in and part of the city. Glasgow's equivalent to those areas would be the nicer parts of the West End,
And the football hooliganism thing is being massively overplayed. You could live your life in either city and be almost oblivious to the existence of football. Some people are just absolutely terrified of football fans (understandable tbf) as they didn't grow up in that sort of environment.
