Synergistic vs. MIT speaker cables- which is best

I am considering the following two cables as an upgrade-Synergistic Element Copper and MIT shotgun 1-3 speaker cables. I have an all krell system feeding an Usher floorstanding speaker. I have no experience with either brand. My current cables both interconnect and speaker are low tier Transparent. Could anyone out there with experience in the cable wars be of any assistance. Thanks so much
