PE house (family owned and sharia compliant) or Investment Banking (deal side)

Hi guys,

I am in a dilemma, choosing between an internship at private equity house or an investment bank that is BB (equivalent to HSBC). I am 20 years old doing a degree in Economics. I've asked friends and family to which they said the bigger the organisation the better for cred on CV! However, a nice small PE house would appreciate me more and I'd learn new stuff given that I've already done some internship at BB.
