MMU attend graduate fashion week. LCF doesn’t and instead often seems to rely on reflected glory from CSM.
No employer employs a degree. They employ a person based on their knowledge, skills and attitude. If you’re happy then you’ll be much more likely to be able to build your skills and experiences both within and beyond your studies. The cost of living in Manchester is also much lower so you’re less likely to be forced into spending every free hour working or commuting just to survive and have free time and energy to do other things.
If you prefer MMU and think that you will thrive there then it’s a better choice.
