Used 1Ds or used 1D Mark IIn?

I have found good deals on both a 1Ds and a 1D Mark IIn for the same price and both in excellent condition.

Except for the crop factor vs. full frame. Which would you have for weddings, low light, enviromental portraits.

What would be the major differences that make your decision?
