Im tempted to write up a big pro vs con post for the 3a Ray Vs Rex. But long story short i think Rex is pretty much the better figure but if i was to keep one of them it would be Ray. And id keep Ray due to sentiment towards the Ray in general not the actual product. But saying that theres nothing wrong with Ray at all, its a must have. But in the future im likely going to sell Rex.
You're definitely one of a kind. I don't know how you let stuff rotate out of your collection like that.
