Front Fork Differences

Hey guys, When I bought my Raid, I also got given a set of what I believe are the open endure front forks. They have the little air nipple at the top. My question is, are their any differences between the two apart from this air nipple and which set are better? Is it worth me swapping over the OE ones?
