BlackRock PAG, MacQ Sales

I am trying to decide between a few internship opportunities. I have an offer in the following 1. BlackRock PAG 2. Macquarie Sales

I know i want to try to get BB S&T when FT recruiting comes around, ideally on the trading side. How would I stack up with other applicants who dont have BB front office experience with either internship? Which one should I choose?

If FT recruiting doesnt pan out and I want to go back to MBA somewhere down the line, which one puts me in a better position for MBA admissions?

Thanks
