I have experience with Canare 4S11. I used 30 foot runs, installed through the wall, down through the sill plate, through the crawl space, back up through the sill plate and through the wall to my loudpeakers.
Four conductors in a star quad geometry with the leads twisted to form two 11 gauge conductors provides superior EMI/RIF rejection to two conductor cabling.
The announcement that "Blue Jeans Cable is a Belden Certified Assembler" indicates that perhaps bluejeanscable.com has a business relationship with Belden that encourages BJC.com to promote Belden over other brands, which might explain BJC.com's endorsement of Belden as their favorite. Something to weigh.
If you are considering the two conductor Belden, I'd suggest buying some Home Depot or Lowe's 12 gauge wire as either is essentially the same as the Belden.
