I know there are lots of collectors. But, since he's asking this question, I question whether he's really collecting for value (if you were, you'd just default to the original).
So, what I'm going to say is, all being the same (no new content, both are the same price, same condition, both at the same place), go with the original. But, otherwise, I wouldn't worry about it. Personally, I'd rather have extra content than the "original"
Then, to be fair, I don't sell games. I am more of a game horder. Then again, most games I really want to replay. Now, this won't get the internet people salivating very much if you post your collection (they usually like either tons of really old complete games or very small collections of "excellent" games in their mind. But, if you want an ego boost, just invite an 8 year old gamer over, and watch their mouth drop open when they see your games.
