This is obviously a purely hypothetical question, as no one would make a sword out of either material.
Although the "diamond sword" would be able to hold a sharper edge, it would be so brittle that; if it didn't snap under it's own weight, it would shatter as soon as you hit anything with any force.
The iron sword would by stronger, but as iron is still a relatively soft metal, it would not be able to hold a very sharp edge and would blunt quickly. You might as well use an iron bar.
So in this hypothetical situation, the iron sword would win.
