Msc Management from Cass or MA Industrial Relations from Warwick?

I am an Economics/Spanish major at a U.S. university and have applied to postgraduate taught degree programs in the U.K. in hopes to pursue employment in the UK/EU. I do however, intend to return to the U.S. within five years of receiving my Masters. My career plans are geared towards management consulting.

Of the schools I have been accepted to, it has come down between Cass and Warwick. Particularly, the MSc Management Program at Cass and Warwick's MA Industrial Relations & HRM Course. I still, however, am awaiting response regarding my application to Warwick's Management Science and Operational Research program.

Can anyone offer any advice about these programs? Besides reading the MBA rankings and a few posts on websites such as these, it is difficult to gauge what programs have the most prestige and are most favored by employers. Moreover, as I will be returning to the US, I want to be sure to select a program that is highly recognized in the States as well. Any advice would be greatly appreciated.
