I've used both, and never found much difference. Interestingly, folks in cold weather climates don't use them (?!?!) I don't get it. I never saw them once, living in Pennsylvania, Michigan or Missouri, or while passing through Wisconsin and Idaho.

Also, don't assume 4x4 helps. It's OK for snow, but does absolutely nothing on ice.
