SOAS vs KCL vs Cambridge for intl relations (Masters)

I hold an MPA from the UK already and am looking to do another Masters online since I already have a job and want to add additional qualifications. I am considering:

1- MA, global diplomacy, SOAS - https://www.soas.ac.uk/cisd/online-programmes/maglobaldiplomacy/
2- MA, Intl. relations, KCL - https://www.kcl.ac.uk/study/postgraduate/taught-courses/international-relations-and-contemporary-war-ma.aspx
3- MSt. Int. relations, Cambridge - https://www.ice.cam.ac.uk/course/mst-international-relations

International prestige of university+course (I am looking for deeper knowledge in data/policy analysis+cost are all factors. SOAS is the cheapest and Cambridge the most expensive. I am aware Cambridge is of course the most prestigious but how does SOAS/KCL's rep fare internationally? I must state that I work for an international NGO that posts me to North America/Canada/Middle East so the prestige factor is perhaps more important than say local employment stats.

Thoughts/advice? Thanks in advance!

If prestige makes a difference, then Cambridge, not only because it's Cambridge, but because it's not an online only course, but has residential periods.

Thank you, but do you really think online only makes a difference to employers? The degrees granted do not state online i.e. there is no actual difference in the degrees granted if attended on campus v/s online
