The primary difference is the brand name on them, a cable with a popular brand name will typically have at least a 300% mark up, an unknown brand will have a negligible mark up.
The more expensive ones may have more shielding but unless you live next door to an electrical substation or a radio transmitter then it is unlikely there will be enough external electrical noise to interfere with the signal on a cheap cable with comparatively little shielding.
You will not be able to see any difference in picture quality or hear any difference in sound quality between different brands of cable.
