Chicago booth vs. London business school MiF - for NYC or London. need help!

Hi, ladies and gentlemen.
I am working on equity/macroeconomic research in East Asia.
Even though my work in current position is quite nice (in terms of salary and lifestyle), I want to move into US/UK financial market to expand my perspective. Thus, I applied business schools and got the admissions from Chicago booth and LBS master in finance.

Now I have to choose between two great schools - I know both schools are powerhouses internationally, but which school will be a better gateway for equity/macro research in sell/buyside in NYC or London?

I slightly prefer London to NYC (I've always wanted to live in European countries), and LBS Master in Finance program is shorter (1 year) and cheaper - those are reasons why I am inclined to LBS. Plus, my boss's close friend is a PM in London, so I think I can leverage this relationship to land an internship job...(just guessing). But Chicago is a great name in financial industry, and I think US financial market is far bigger than UK one. In addition, rent in Chicago is much cheaper than London. So (rent + cost of living) will partly offset higher tuition of 2 year MBA.
Realistically, however, because I do not have working visas for both countries, I guess LBS with 1 year and cheaper tuition is a safer bet if I come back to current position.

In my country, Chicago and LBS have similar reputation and alumni base - a notch below Wharton. Plus, I am going to go school with my wife and daughter, which city will be safer...or better to stay? Any input will be really helpful to me. Thank you for reading!
