Reinsurance vs. MM IB Internship

Trying to decide between MM IB, Reinsurance, or Macro Research position for summer internship. Obviously, reinsurance is a niche sector, but the firm is well respected and has great exit opportunities. The Marco Research firm is relatively young but is affiliated with a top MM IB. Also, it has a relatively small but close-knit team and was co-founded by alumni from my school. MM IB seems like it should a no-brainer but for some reason I have a good feeling about the other two positions. For perspective – comp is similar at entry level for MM IB and Reinsurance but slightly less in Macro Research, all are in NYC, and I’m a Junior at a non-target. Looking for advice on which path to take. Thanks
