Howdy Brent,
I favor the look of the 3/4/500. If I had to choose one on just off road ability it would be the 3/4/5000. From what I have heard it has more articulation and frame flex than the 3/4/500. Also there are more things hanging lower on the 3/4/500. If I was forced to take either one I guess I could find room on the property
