M.Ed or MA

Here is an odd one for those of you with diet pill of the mind . . .

Should I get a M.Ed or an MA in subject specific topic. I really happen to like the idea of doing some work in History.

I am leaning towards one in history as that is my forte. The real problem is will not having an M.Ed hurt me?

This is what I would like to know. So if you have any suggestions i would be open.

Well I hope that you have a most happy day.
