Cass business school (banking & finance) vs SOAS BSc Economics Urgent!!!

hi,
I'm applying this month for universities and I am really unsure about whether to apply to Cass for banking and international finance or SOAS for BSc Economics.

I hear people pick cass over lse for some subjects..
i know Cass has a good reputation for the finance careers but and SOAS is a Good university in general.
I want to keep my career options open after my degree, but i know Cass is likely to get me a good career but it will be specific to the banking and finance world.

Don't know much about SOAS but they seem a good uni for economics which I really like.
my other choices are economics in LSE, UCL and Queen Mary. I want to be secured with a place in a good university and UCL or LSE are competitive and i might not even get an offer for them. I choose QM because they want AAB which would be my insurance.
Also, how is the social life in both, how are the tutors and which is better in general.
thanks
