I think it would help looking at employable scales for each uni if thats what your concerned about. I am at Sheffield, when it comes to helping better employable skills our career service is really good, they also integrate the skills you will need in the working world in the course too. We have a careers fair every year and online calls with employees on a weekly basis, who tell you thier journey after sheffield. Compared to other city Universities Sheffield is much cheaper, living cost wise, from what ive heard from my friends that go to other russel group unis.
I am not to sure about Birmingham to be able to make a fair comparison.
Hope that helps!
