Using the trainer plugged in vs not plugged in

Hi, Have had a tacx neo for a short while now, and i have always used it unplugged mainly on Zwift. Question i have is what is the difference (if any) or using it plugged vs unplugged.

Is the more common use case using in plugged in?

Thanks

If it's plugged in and you stop pedaling the freehub will continue spinning and you will hear the bearings clicking just like your rear wheel does when you are not pedaling. This freewheel simulation is only possible when using the power/plug. When not plugged in, this stops after a couple of seconds, whereas when plugged in and, for example descending a slope, it will happen until the bike stops.
