Cables IIRC the spec, give you about 40% more traction than a std hwy tire. Studs around 9%, with std chain chains being 100%.
So depending upon the what you are driving in and on, choose your poison. Cables are not that good from my personal experience vs chain chains.
IIRC, michigan and a few other midwest states do not allow chains on vehicles....so use them at your own description. Here in the NW/puget sound area, I'll take the chain chains! I've seen way the heck too many metro buses stuck with cables.
