Bain or BCG? NYC office, Summer intern

I recently received offers from both Bain and BCG and am trying to think through the decision in the most thoughtful way possible.

Right now, I feel especially drawn to Bain. I really enjoyed the people I met throughout the process, and the culture felt very genuine to me. The team atmosphere, quality of life, and overall “airport test” all stood out. I had a great experience in my Bain interviews and genuinely felt like I could see myself working with the people there.

With BCG, I am still very grateful and excited about the opportunity, but I felt a little less certain throughout the process. I did not necessarily click / feel the same effortless experience when talking to people throughout the process. That said, I want to make sure I am not making this decision based only on culture or interview feel.

I do not yet know what practice area I want to go into. Longer term, I have a vague interest in startups, entrepreneurship, or possibly building something of my own. I do not think I want to stay in consulting long term, but I am also open to the possibility that my goals could change once I start.

For people who have had to choose between Bain and BCG, or who have worked at either firm, what factors would you recommend thinking through beyond culture? How should I weigh things like office strength, staffing model, exit opportunities, startup/entrepreneurial exits, mentorship, training, and general lifestyle?

I would really appreciate any advice on how to approach the decision and what questions I should be asking before choosing.
