Most of the people outside of the NW have sidehills and the Rahco sidehill is significantly different than its hillside version so it probably isn't a good comparison. Hillco's sidehill and hillside are similiar. Cost wise I know the Hillco hillside is substantially less than the Rahco. Don't know about sidehill though. Both have their advantages. I see from your pic you are running Rahco's. How do you like them?
