帝国金融or诺大金融?

I am hesitant about choosing between Imperial MSc Finance and Nottingham MA Finance & Investment.
The former's tuition fee is almost twice as much as the latter, not to mention the high living expenses in London.
The crucial point is that I am aiming for a career in corporate finance or M&A services in companies like big 4, is the deep quant stuff in IC Finance really that helpful for this kind of job? Maybe...a qualification like CICPA or ACCA or CFA is more useful.....
Any opinions are welcome and thanx very much!!!
