Elite Boutique v. Mid Size HF v. Megafunds

In the vein of many prior threads, I have a decision problem going into next summer for my rising senior summer internship. I currently have an offer from an extremely well-run credit fund that is fairly large, has a long track record, and is growing. (Unnamed to preserve some measure of anonymity) I also have an offer from an elite boutique investment bank along the lines of Moelis, Perella, and Allen & Co. Currently going through recruiting with the megafunds with strong training programs like P72 or Bridgewater.

Looking forward, I do want to be on the buy-side, but also want a measure of job security and a bit of a life after 8 or 10 years of work.

With that information, what do you guys think exit opps would like between highly specialized HF and elite boutique bank? Same for business school applications.
