Hi Jim...

both are important equally ...  

as far as VA   that is the volts times the amps    thus  a pole pig that 
has 4400 VA  if it is running at 14,000 volts will have .314 amps on the 
secondary side.   ( VA is kinda = to watts )
and on the other hand   if the pole pig is using 240 into the 
primary.... it will draw 18 amps to produce 4400 VA. ( approximately 
4400 watts)

as far as which NST is better

lets see   9000 X .060 = 540 VA
                12000 X .030 =  360VA

the 9/60 has more punch

the 9/60  will pull  about 4.5 - 5.5 amps -at- 120 V
the 12/30 will pull about 3 - 4  amps -at- 120 V

( need to throw in an extra amp or so due to the core currents in the 
transformer)
