I would never agree to an arranged marriage. This is mainly because (1) I don't like the idea of giving up control of who I'm going to spend the rest of my life with, and (2) my parents had a very specific plan for my life, which I have largely diverged from, and so any mate they might have selected for me would be totally unsuitable.
A family friend (of my parents' generation) did have his marriage arranged for him, and he and his wife were very happy together. So it can work out very well... but it's not for me. My husband and I arranged our own marriage, dang it
