I find myself in a bind when it comes to choosing between these two universities, so any information would be greatly appreciated.
I am an international student from Eastern Europe with no real work experience. Also. after my postgrad studies I plan to work in the UK, if possible.
Anyway, which of these business schools is more reputable and has better employment prospects?
Additionally, do many non-financial firms target these schools? I am not keen on working in the financial sector, but do not feel an aversion to it if an opportunity should arise.

Aston has a better track record with MSc students than Henley and, for example, is in the FTs MSc ranking. Henley's finance courses are excellent, in the ISMA centre.

Both these programmes seems very academic and research oriented. If you want to maximise your chances of work, then take an MSc with the word 'management. ' in the title, which includes courses on managing money, people, projects, resources.... etc.

Could you explain in what terms does Aston have a better track record? Also, in the FT Masters in Management rankings the Aston course rated is actually MSc International Business, so is this course generally well regarded in the management field?

Aston has has a larger MSc portfolio for a longer period of time.

The best measure of the strong regard of the programme is the excellent placement rate and high salaries for alumni. I think all the schools in the FT ranking are well regarded. Unlike many other internationally-oriented MSc programmes in the US, Aston gives students many options for international study visits, especially in Europe, and exchange programmes. It also has a very skill-based approach.

Thanks a lot Duncan! You've helped me a great deal. I have made up my mind and will opt for Aston.

Yes Aston is a better option then Henley for MSc programs.

Just out of curiosity, how would you rate Lancaster University Management School compared to Aston?

Aston has an advantage over Lancaster due to its location and strong connections with industry. but if you have an option of Bradford then it would be even better as its MSc is ranked 36th
