threadless is a smart system to use, and convenient.

but aesthetically I say a threadless fork needs to be used. 1 inch threadless headsets and 1 inch threadless forks are readily available in carbon or even lugged steel.

edit...
and a quick easy trick- buy a used (or nos) period/brand correct fork that's way too tall for your bike, cut off the excess (threads should be way above stem height), add starnut to steerer tube, and you have a proper c&v threadless system that ideally even matches your bike/paint.
