Answer to OP:
I took the personal accounts of people students I knew personally, and graduates with significant experience in their workplace, when choosing which university to apply for. In summary; I was always advised to be weary of information on Edinburgh Uni that might be bloated by it's reputation, and that Strathclyde is far-an-away the best in Scotland for anything Design/Engineering related (i.e architecture in your case.) Edinburgh has been said to under-support some courses and to be a difficult place for some students to go to Uni.
Don't misunderstand me though, I know Edinburgh to be a great University in what is perhaps one of the world's prettiest cities, however the uni isn't for everyone and it certainly isn't for every course. I know the University offers a great course in Politics& Int. relations, for example.
^ Just the advice I received. Note: I'm about to study Engineering after not applying to Edinburgh. Going to eith Uni should get you educated and noticed in an architect's world.
