As a transfer, it’ll be easier socially if you go somewhere where you can do what you enjoy as that’ll make it easier to meet people. Based on what you wrote above, that would be Kenyon, where the music program is stronger. The upside of isolated schools is that life happens on campus and in the community - that can be an upside as you fit into your new home.
At either, you will need to make research opportunities happen, but there are probably plenty. It sounds like you prefer Kenyon, and it sounds like a good choice. You will get a great education at either.
