Why not just sign up for all three?
Over 77% of the world's airlines belong to one of the three alliances these days so it makes sense to just join a FFP on each of the three alliances. That way you're 77% covered that the airline you'll be travelling will earn miles on either AA (or any other oneworld carrier of your choice), DL (or any other SkyTeam carrier of your choice) or UA (or any other Star Alliance carrier of your choice).
