University of Tokyo or University of Osaka?

Hi, my University has offered me an exchange for 10-11 months for these universities:
University of Tokyo, University of Osaka (and ICU, but I'm putting that as my 3rd option)

Both universities are good, and both seem to teach standard Japanese. I'm less so concerned about the school, and more so about the cities.

I'm very torn between choosing Osaka or Tokyo for this amount of time. I had spent a minimal amount of time in both while traveling. I found that I did not really enjoy Dotonbori, but enjoyed the quiet parts of Osaka. As for Tokyo, I really enjoyed it because it was so exiting, but I'm afraid that the staying in that metropolis for so long might get draining.

I'm not really into a crazy night life, and I'd rather spend my nights in a suburban area with a calm bar or two.

My goal is to learn the language and hopefully make friends with a few locals! I was wondering if the people on this sub have any advice or insights on my dilemma.

Thank you!
