I would keep what I shoot best and trade/sell the rest (unless it has some strong sentimental or high collector value).

I'm a shooter first and a collector a distant second. If you get it make sure it fits you properly. It would be a mighty bitter pill to swallow to trade guns you can shoot for a gun you can not shoot.

I'm affraid the right answer really will come down to what you value most, and that's something only you can answer. Good luck with whatever you choose.
