Investor relations MM PE London

Hi gang, 

Currently, just graduating uni, have an FT offer for a boutique investment bank covering FIG.

Interesting dilemma here, was recruiting for IR internships earlier in the process, and just got an offer for a MM PE IR role (internship) - Would still take the IB offer as it is FT (starts later in the year) but would it be worth just doing the IR internship. Would it add any value or would chilling pre-FT make more sense (internship and FT does not overlap) 

Thanks Gang, 

Chimpa
