CASS v BPP v SOAS?

I'm currently in year 12 and looking to study an undergraduate degree in investment or finance to hopefully gain a job in the finance sector (IB). I was just wondering which of these universities is best (i.e. best courses, teachers, facilities, graduate prospects,networking, entry standards etc) or if there are any other good universities in London for a finance related degree apart from LSE. Any information would be greatly appreciated, thank you for your help!
