when a forum member writes a question like this: what speaks to you most and all the rest. And for the most part, that is true. I truly believe that you should be with the watch that speaks to you. You have to wear it and look at it!
However, in this instance, and with this choice, I think its obvious. Keep the RM002 - especially if in platinum. First, the platinum cased versions of this watch, with a carbon plate are rare. Dont know of many (a handful). Second, the RM002 is the watch that made it all happen for Richard. Any other special edition (with a couple of exceptions) has this movement behind it, including the RM003. Third, it is a very 'pure' watch. It has all the essentials that Richard was looking for in his performance watch.
The RM003 is great: and quite a unique combination: tourbillon and second timezone..... but, the RM002 is a pure watch.
But if you do sell the RM002 - it seems you have plenty of interest already on this forum!

Good luck!
