It makes sense if your carburetors are in very good working order and 
you spend much of your time at full throttle. However, if the carb bores 
and throttle edges are showing a little wear from the throttles being 
snapped shut, throttle bushes worn a bit, and you're using the car to 
toodle around town and spend a lot of time at idle and part-throttle, 
the idle synchronization method is better. Throttle plate and bore 
irregularities show up much more at idle than at full throttle.


The method of synchronizing at idle is probably secondary.  I suspect 
that using a Unisyn (or a similar device) probably can produce more 
accurate results, if employed properly, but, likely only a bit better 
results than those achieved by sticking a tube in one's ear and paying 
attention.


Cheers.
