MBB internship decision - between bcg and bain

Hello,

I’m very fortunate to have offers from both Bain and BCG. Long term, I’d like to start my own company or join an early-stage startup, and I’m trying to think about this decision beyond just the first few years.

For those who’ve worked at either firm (or both), how did your experience shape the way you think and work? Did one environment better prepare you for entrepreneurship? Any advice or things you wish you’d known would be much appreciated.

Thanks in advance and really grateful for any perspectives.
