Does CAT6 cabling differ in quality?

Setting aside obvious cable standards such as Cat6a, and the type of cable UTP, STP, etc, I’m curious as to whether the quality of Cat6 can differ and in what way?

I’ve purchased some fairly cheap CAT6 UTP at 100m for 60 AUD, looking at electrical wholesalers it seems most of them charge around double this for around the same length and cable type - what am I missing out on going the cheaper cable? is there any reason not to go the cheaper one?

For reference the brand of cable is Anyware.

Let me know guys!
