Either - because no-one is going to care where you did an MPharm. Its a GPhC accredited degree with a set syllabus. There is no 'better' Uni. You get exactly the same degree at the end of the 4 years. The NHS is not going to care where you went to Uni - and neither will your future patients. Pick the environment that will suit you best, and where you will feel happiest - and if you think that is MCR, then that's fine.
