Which is more qualified an Facp or an MD?

I don't know what you are referring to. FACP can stand for the following.

• A Fellow in the American College of Physicians (ACP)
• A board certified internal medicine physician in the United States.
• A Fellow in the American College of Psychiatry

In terms of medicine, a Fellow can be one of equal ranking as a peer, or a memeber of a learned society, or a graduate student appointed to a position granting financial aid and providing for further study. Thus, an MD is an MD, a student is a student.
