Cerberus VS Big 4

So I’ve the option to choose between one of the two in a less known office (Georgia, Cyprus, Portugal).

For Cerberus, I’ll have the typical responsibilities of a PE intern. For Big 4, I’ll most probably have some sort of tax or accounting role. Given my goals are to land an IB SA role in London next year (I study in the UK), would going to Cerberus give better odds at breaking into IB or will it not make much difference.

Thanks in advance!
