Yo,
I am currently in the QFIN at WU Vienna. The decision heavily depends on your background. If you come from a business background, you will have a tough time in Vienna (in most cases) with the challenging stuff that you gonna learn. While most students get to know each other in weekly parties etc. you will spend most of your "social time" doing homework with them. Furthermore, you will learn a lot of theoretical stuff here. It is a lot of maths. But if you already did a lot of maths in your bachelors, its gonna be rather easy most of the time. A big plus is the fact that you will have professors who spent significant time in Wharton, Princeton, etc. And Prof. Hornik (director of the programme and who teaches a lot) is just a genius.
And btw, we also have a bloomberg terminal afaik

(although access is somewhat restricted)
But judging from your post, I wouldnt recommend going to WU.
