Difference between these cables?

I need one of these.

Akasa USB 3.0 internal adapter cable £5.99

and

BitFenix Internal USB 3.0 £7.99

I'm assuming the only differences are the words "Bitfenix" and "Akasa" and one being 33% more expensive. Why would anyone buy the Bitfenix cable and why would anyone think stocking both is a good idea?

I did look for length difference. Obviously not hard enough.

10mm/1cm isn't anywhere near enough to warrant the price difference, though. I'll go with the akasa, it only has to be long enough to go through the grommet right beside the header.
