The real reason for some countries have 220v/50Hz ( or between 49 and 50
Hz like sometime frequency is in the East of Europe ) are the equipment
and not concern about neon bulbs, television or our health.
After all huge transformers have been built for 10Kv or 20Kv to 380V
( this men 220V betwen each phase and ground ) it's to difficult to switch
to a better standard.
However 120/60Hz is not one of these...like SECAM is not better than PAL
