I own this cable now for 3 years and it's my main cable between guitar & pedals so intensely used. It has a solid shielding and quality connectors, not a sign of wear after this time.
As it's 'coiled', don't be surprised that it looks short at first sight. As you can't stretch it completely you won't get 9m distance. So I would advise the 9m variant to the 6m, the advantage of coiled cables is that they don't tangle up as much as normal cables.
The biggest argument for these cables is when you accidentally step on the cable: no problem with a coiled cable, embarrasment or worse with a classic cable.
I'm very happy to have found this product as I've worn through some other coiled cables in the past.
