Cable is something I just don't get worked up over, as a rule. As long as the quality of the wire and build are good, you'll be fine.
Since you are considering Monster:
A client traded me a reel of Monster cable that I found to be some of the lousiest cable I have ever had the misfortune to work with. Both the hot and cold conductors were covered by a black film, such that it was challenging to see which color I was working with. Trying to remove that coating would often strip the colored wire insulation off as well. Very frustrating, and very flaky. I still have half of the reel sitting here unused. I can make a cable with Mogami or Canare in literally a quarter of the time and know that it will turn out better every time. I don't know if all Monster cable is like this, but between my frustration with the wire I worked with, and the company's well documented shoddy business practices, I avoid their products like the plague. My $.02.
Edit: One more kvetch- the insulators tended to start melting at a much lower temperature than other cable I am used to working with...
