Finally had an opportunity to test this -- and I can confirm that on at least a couple of my larger neon signs, the tubes shut off differently using the pull chain switch than they do using the line cord.
I have one large Boulevard Brewing sign, for example, that shuts off slowly, with the long border tube being the last to de-energize, in four distinct segments, when unplugged. By contrast, the entire sign shuts off immediately when I use the switch. So I can only conclude that the power supply must be bled down quickly when the switch is toggled.
