The softer ergo's and slightly thicker handle of the II make it more comfortable for the light camp chores and the yard work people want to do with it. The Rajah I's aluminum frame is slimmer which makes it print less, but the frames ergo's aren't as radiused. The build quality on it isn't up to snuff with the Espada series, and I think that's the niche the RajahI was supposed to fit into. Hold a large espada next to the Rajah I and you'll see why they dropped it. Wish I had a better photo comparing the ergo's...
