Snow Chain vs Cable

Mrs Cad is soon moving to Colorado Springs. Well actually Peyton about 30 min outside of the Springs on Hwy 24. She will be using either a Ford Mustang GT or a Dodge SRT-4.

I remember when snow tire cables came out they were the best, but I suspect that it was for smoother ride than for any real traction advantage. Those of you with experience in the snow and ice, is it better to get the diamond pattern chains, z pattern cable, or something else. Note: better is a combination of driving smoothness, traction, and all else being equal, ease to put on.
