What is the better one to use any idea if is shielded better than the other?

The Monster 300 cost double but should I pay for the name or is there an actual difference. Hard time trying to find reviews on cables.

Thank for any help in advance!

Personally, I would not fall into the Monster hype. Save your money and get Radio Shack Gold series, RCA, or equivelant. This question comes up very often on the board, and the general feedback is your paying for the name, similar to BOSE

Paul, welcome. One reason that there's a hard time finding reviews on cables is that there's practically nothing to review(and so the "reviewer" has to exercise his imagination). Cables are essentially commodity items once the wire and connectors meet basic specifications and can be bought on the basis of price. Monster products are generally grossly overpriced and there's no good reason to consider them. Very little technical info is available from the Monsters on their cabling, including the description of the shielding. In any case, the connector to the sub has about the easiest job in all of audio, since it only has to carry an analog signal from about 20-100Hz. No digital consideration is relevant and in most cases the shielding used on cables that sell for about $10 U.S. for a 10 foot length is fine, so there's no good reason to pay more. Enjoy your Axioms.
