MM REPE vs. BB/EB IB for Summer Analyst/post grad

I am a sophomore at a top ivy (HYP) and am trying to decide what my best path is. On the one hand, I've gotten indications that I will likely receive an offer soon from a MM REPE shop (around the middle of the PERE 100 list) that I vibed really well with. On the other hand, I've also been preparing to enter formal recruitment for the major BBs and EBs. I'm inclined to go with the former offer (which will probably come before any potential banking offers) given how much I liked the firm and the fact that my ultimate goal has been to work in PE. My level of excitement about that opportunity is just a lot greater than working in banking.

But I'm wondering if it might be a mistake to miss out on having the classic analyst program experience under my belt, as well as having a brand-name BB on my resume (obviously need to account for the sizable risk I don't get an offer at one of those). I'm also curious how severely working in MM REPE out of undergrad (as opposed to corporate PE) pigeonholes me in terms of exit opps to other asset-classes and fund sizes—I've realized I'm really really interested in real estate, but haven't had actual experience yet so can't fully confirm thats what I want to do for my whole career. I've been told that b-school acts as a sort of "reset" in that respect, but not sure if that's accurate. Would really appreciate any and all advice on this.
