Which Internship is Better?

Currently have a sales internship at a brokerage firm. Decent pay but I cannot imagine doing this for 3 months. Looking at the following two internships, no guarantee that I get either one, but I have a small network at both.

Bulge Bracket, Los Angeles Branch: Private Wealth Management

or

No Name IB Boutique, Los Angeles.

BB PWM is fairly straight forward. Here is a description of what the Boutique entails, from their website:

1) Detailed financial modeling
2) Market / industry research
3) Client-ready pitchbook and deal document preparation
4) Transaction due diligence

In reality they will probably have us grabbing coffee and dry cleaning, but as long as I have great coworkers I am satisfied doing any kind of work. At the end of the day, I want to be an IB analyst in San Francisco or LA. What are the pros and cons of each? Which internship would you take if you were in my position? I am a college junior, non-target, 3.7 GPA, Back-Office Accounting experience at a no name (essentially useless). Thanks for the help!
