Unless the difference in 'employability' is huge, then that shouldn't influence you. Re CIM qualifications, employers like them, but they also value experience so if the courses offer you work placements, that is a great start. Also, do as many marketing things in your own time (eg working on student media - blogs/magazines) as that will help build up your skills. You might want to contact the universities directly about their CIM accreditation (or ask when you visit), but many people gain CIM qualifications in their own time, through self funding or occasionally via sponsorship from their employer. If an employer does have a marketing department (often very small), it is unlikely that most will care which place you went to - or whether you have an actual degree in the subject. Your ability to get results (via a great campaign or via improving the image of the company) will be one of the criteria for success. So, go for the place that appeals to you the most, is my advice.
