Hi there,
I would recommend breaking it down by; modules you can take, what support each university offers (academic and wellbeing), what the university's careers service offers, and also who your tutors at these places will be. Is there a certain field that you are most interested in? What research do they currently do?
When making big decisions, sometimes it can be helpful just to write a pros and cons list to help you see what things matter to you most.
Good luck!
