No brainer - WBS is far more reputed. The biggest challenge Cranfield SM graduates face is that the Cranfield SOM is not known to most recruiters, in my experience (you may independently confirm this from the current and past students). For the same/similar fee, WBS/WMG offers a much better value and a well-recognised brand for life. Also, getting into WBS is very tough compared to Cranfield SOM - this translates into a better overall cohort of students and a great learning experience. Having spoken to many friends who graduated from Warwick, I learnt that there are many regular guest sessions conducted by leaders working in large organisations - something you may miss at Cranfield, unless things have changed. I do not think anybody should choose the Cranfield SM MSc course over WBS Marketing MSc. Regarding getting a job in the UK, it will not matter which of these two universities you go to. For the overall value and your learning experience, WBS is better. For further insight, please look at a) Graduate outcomes b) The Acceptance rate, of both the schools.
