The best "look" is no wiper arms/blades (although not legal nor sensible in a heavy rain).
They're not for everyone and most make your car look tacky and cheap.
They are for kids - like coloured wheel nuts, coloured valve caps, big chrommies, mini boxing gloves, dumped on arse. The Queen street spec.
Having said that I do run a set on my 32GTR, same colour as the body, and personally they suit.
