The difference and reason why neon is not used is that in winter outdoor
tubes will start red.... 
Imagine the customers face when his nice white sign on his roof 
 turned red when switched on. 
It's a nice effect with HF excitation and different tube diameters. 
You can see examples in Rudi Stern's books - David Swenson's dance levitation 
series in example. 
(Or Dave Ablon's  "flip the switch")
