If you had to choose between the two, where would you rather live? I think for me, living on the moon would be more ideal, because I could potentially go back to earth one day. But if you live on Mars for example, I don't think you can come back, so your life stays on Mars until you die. I don't think I could take that, so living on the moon would be a lot more appealing to me. I like the idea of being able to one day go back to earth, and with Mars you really can't do that.
