Of a practical nature, most 50Hz equipment will work as well on 60Hz unless rotation speed is critical (older phonographs for example). Most 60 Hz equipment will work on 50Hz unless it is operating near its heat limit or rotation speed is critical.
60 Hz is well above the "flicker" level, but 50Hz is almost as good.
60Hz uses less iron in inductors (of interest to poco's) which is why aircraft use 400Hz to save weight.
50Hz is more "Metric".
110v is safer, a good compromize between I**2 R loss and danger.
(Navy uses three ph floating neutral on ships, only 60v to the hull on each leg, a shorted phase (not uncommon) still provides light, and the delta connection allows a transformer to be changed out without loosing power, survivability issue)
220 single pole is a way to provide more power over distribution systems extant. (this I was told while living in Bangkok)
