Pinside puts the value of both at nearly the same. I say keep the original and sell the remake while you can still get the most money for it... originals will never be produced again but remakes will, at least for the foreseeable future, and there is a certain charm to owning a piece of history.
If you're a purist it's not even a question. In every hobby there are purists who will only buy/own originals. It's why people fully restore classic cars and spend countless hours searching for original stock parts. As a collector, there is no alternative.
But if you're just in the hobby to have the most fun possible, the remake brings a lot to the table.
