I have not heard either cable, but do know both are quality manufacturers. The Monster you specified is a biwire cable...if memory serves. The other is offered in uniwire or biwire (had to cheat on that one, and look it up!). They also differ in price, as Monster is almost twice the price. Keep in mind that this does not mean they are better - simply they cost more.
I have used Monster (as well as others) before, and think that unless you have a "true hifi" system, basic speaker cables are all that is really needed. There are two schools of thought on cables:
1- they dramatically impact the performance and sound of the system: buy very good quality,
2- they do not dramatically impact the performance and sound of the system: buy decent gauge from a local electrical supplier.
I believe cables are the finishing touches to an already good (or above) system. You should at minimum purchase 12gauge "bulk generic" cable.
Interconnects are somewhat different, but the arguement is the same.
I make these recommendations without knowing your pieces. It could be wrong if you have hifi pieces.
