Because neither of those links give the brand/manufacturer of the hose, I couldn't tell you.
If you are looking for lightweight and flexible, you would go one way, if you are looking for durable and long-lasting, you would go another. You give up one set to get the other. Superflex is a trade name for hose made by Amflex. I liked the Amflex hose because it's lightweight and flexible for the last section of hose. You will cut it down every so often because of kinking, but it's worth it for the ease of use in the home. I liked to run heavier hose, like Flexaust on the rest of the reel for durability and longevity.
BTW - Amflex makes/made several different weights of flexible hose designed for everything from portys and the car wash industry up to very heavy hose for the sewage sucking industry. Joe and Greenie have done a lot of work directly with the manufacturers to develop a TM hose that was as light and flexible as possible, but still as durable as possible, and there were many variations leaning one way or another that both Jeff and Joe sold.
Take care,
