Anti-social culture? Reed has a high level of introverts. It is a comfortable place for those who are not very social, but I would not call it anti social.
I can’t tell you much about Kenyon but Reed has a qualifying exam Jr year. I would speak to someone from the school to see how ready you will be for that exam coming in as a transfer. I would also double check with both to see how well your courses transfer. My son did dual enrollment at a CC in the Los Angeles area and when describing one of his courses to his adviser he received a facepalm and a requirement to repeat the course.
You may also need to take the freshman humanities course even though you are a transfer. I would check.
That being said, I always vote for Reed but it is not for everyone.
Feel free to PM if you have questions. My son is currently at Reed.
