Well the other difference is if you are running on or over heating ducts you need plenum rated. I didn't even know you could get stranded 6e cable. You also need different crimpers or die's for solid core versus stranded core cables. Unless you need 6e for something specific, 5e is fine for almost all applications, and usually cheaper.

We get all our bulk cables through distributors - if you have a company you can register with a lot of electrical suppliers and get better pricing. We use mostly General Cable bulk cabling now and have had great results. A good tester is important as well to certify the crimps and pins.
