Biomedical Engineering in QMUL 2019

Hi. I've got offers for MSc in Biomedical Engineering from both QMUL and Sheffield. I'm confused as to which one to pick as I find that both the unis are equally good except that QM is in London and is highly reputed thereby having an edge over Sheffield. But since Sheffield has a higher ranking than QMUL, it makes me think that Sheffield is better but I'm not sure though. How good is this course in both the unis? I'm an international student and I desperately need some help with choosing the right uni for me. Thanks.
