doesn't Benjamin + Crosman + Gamo = Begonia ?
You are asking about two lower quality manufacturers, each with their own issues. If you are looking for accuracy out of the box, and a better chance of frustration free shooting, try something German. You will spend a little more initially but be money ahead in the long run. crosman/benjamin break barrels have an abysmal record for out of the box shootability and function. I've had one; that was enough, tk
