Might as well go CAT 6A if you want more than cat 6.
6e not being a recognized standard the brand is very important.
I dont think there is any place for cat 7 or 8 in a home without being massive overkill and unneeded.. Also if buying online I wouldn't trust a cat 7 or 8 rating from Amazon for example. CCA wire is a real issue too.
People shopping for cat 7 online who don't know better end up with flat 32gauge cable etc.
And that one is amazon brand.. yes they put their name on it.
For normal sized home distances most quality CAT 6 will do 10Gbit... although CAT 6A is preferred.
