Very, very much in the eye of the beholder, but here goes:
Argento Flow series: sober, timeless design, very much on account of the connectors
berTram ProXima series: no, I'm not drunk, that's the way it's written and the cables look just as flashy and unique (I believe)
Siltech Royal Signature series
Luckily, all of these are also in the Champion's League in terms of performance (sadly, also in terms of cost)
