Which to choose?

Hi all! Would be very grateful for your help making the following decision.

I have received two offers: 

1. Commercial Banking Analyst at Citi
   1. Pro: brand name and FT offer
   2. Con: commercial banking - apparently little exposure to IB, pay won't increase a lot
2. Coverage 12-month off-cycle internship at one of the main french banks (SocGen, Natixis, Credit Agricole)
   1. Pro: not a pure M&A role but according to interviewers, a lot of IB exposure
   2. Con: internship rather than FT, uncertainty around conversion, coverage can essentially be CB as well

Thanks in advance! Would appreciate any insights you may have.
