Analyst internship at family office VS Middle Office IB

Good day community,

I am current a postgraduate student pursuing a Masters in Finance from Singapore. I am offered an investment analyst internship at a front office and a middle office (Global Banking) position at a IB. My end goal would be to secure a position at any front office roles (M&A/DCM preferably) of a BB Bank. Hence, I am conflicted between which offer to accept as I recognise that my resume does not have enough branding and the Global Banking internship at the IB would boost my resume a little but it’s not focused on investments which is something I would like to pursue in the long term. May I know which offer would be a better route?
