LSE ISPP v UCL Social Sciences with Data Science v KCL Social Science

Hello! I've gotten offers from the universities above, however I remain unsure which one to firm and insure. If there's anyone who's studying these courses, could you give me a bit of an insight around how you're finding the course, how supportive is the university in relation to finding internships/work experience, how the social life is, what societies are like and just in general if you are enjoying your time! Thank you
