Dilemma - Sophia’s FLA or Waseda’s SILS?

Hello everyone, I just found out that I received unconditional offers for both Waseda's SILS program, as well as Sophia's FLA program. However, I am very much torn as to which university I should matriculate to. I've heard Waseda's prestigious name will carry me far in employment, both in Japan and my home country (Singapore). However, I've heard that SILS is " easy " and " only for Japanese students who want to improve their English." On the other hand, Sophia's FLA program is well reputed and offers more rigour for native english speakers, albeit the university's less-renowned name. Has anyone been accepted to both colleges but had strong conviction to choose one over the other? Any help and advice on this matter will really help me out. Thank you!
