Analytics and Sales Internship at Bloomberg or Pension Actuarial Intern at Isio?

Hi, everyone! I have received two internship offers and I do not know which one to pick. The first one is in Analytics and Sales Intern at Bloomberg London. Bloomberg sounds fine, but Analytics and Sales is a department with people answering phone calls pretty much and with not many future advantages if I would want to use the internship to get a full time offer. The second one is Pension Actuarial Intern at Isio, the new name of KPMG's pension advisory department, which has just separated from the main company. It is in Birmingham, the salary is fine, but the company is not so well-known so far. What do you think would be better for my future? Thanks a lot!
