Levfin internship to IB

Hey everyone, Seeking for advice.

I am a year 2 finance student looking to break into IB (M&A preferably).

I received an offer from bnnp for an off-cycle internship in their acquisition financing / Loan capital markets team.

I also have an offer lined up for summer internship in M&A at a regional boutique (small cap).

Since I’m hoping to land an offer at a BB in M&A by the end of my studies (in 2 years time), what would be preferable to choose?

Though bnpp carries much more weight, a bit concerned that an experience in the capital markets division would restrict from future offers in M&A.

Thanks for the help!
