UCL EUROPEAN SOCIAL AND POLITICAL STUDIES with German or French

I am looking into the possibility of applying to study EUROPEAN SOCIAL AND POLITICAL STUDIES at UCL. I don't want to apply to the SciencesPo program. Does it make more sense to do it with French or with German?

My preference is with German unless there is a reason to choose French instead. I am graduating from a French school but with a joint German/French high school diploma. So I am mother tongue English/French and C1 level in German. Thanks for the feedback.

After the course I plan to either do a French/German MA (SciencesPo and German university) or do a law degree in the USA. I can legally work in EU and USA but not in the UK.
