depth vs breadth dilemma

[DecisionDilemmaDread]

Hey everyone! 

I have a rather difficult decision before me, I would really appreciate help

I am a student from India (woman) with a Bachelors' degree in Polymer Science and Technology GRE 339/ TOEFL 119/ GPA 3.95

I have acceptances to 1)UIUC - Materials Science and Engineering and 2)UMich Ann Arbor - Macromolecular Science and Engineering (both for Masters, funded)

Which of the universities would offer me better opportunities in terms of jobs in the industry? The basic dilemma lies in whether I should choose to diversify my field by joining a materials science program or whether I must delve deeper into polymer and macromolecular science studies. 

Thank you in advance for your inputs!
