As in Europe & North America

The difference is in line loss when you "transport" the power along a cable. A cable feeding a (say) 10,000 Watt consumer must be thicker at 110 Volt than a cable feeding the same power under 220 Volt condition.
So you need "more copper" in a 110 Volt installation, compared to a 220 Volt one.
If you would use the same copper thickness in both cases, then you lose more voltage along a 110V line than on a 220V line, if wattage was supposed to be the same in both cases.

110 has no particular advantage over 220. One will kill you just as dead as the other. For 110 volt circuits to do the same amount of work (watts) as 220, it requires twice the current (amps) and larger gauge wire. That's why, in the USA, most high power appliances use 220 volts. This is to avoid having to use 8 AWG wire which would be quite expensive. So, there's no real advantage in going with 110 volts.

If you touch the live wire the danger is less in 110 volt. May not lead to death. But transmission is difficult. You must have step down transformer kept at a shorter distances. Only USA & Canada are maintaining the 110 volt of course they are rich country. Other countries are maintaining 220 vots transmission line . Dangerous to the man kind. But maintainig cost will be cheaper.

Higher voltages are more efficient that's why commercial lighting in most offices use 277 volts. The two phase voltage of 277 volts is 480 volts.
The possibility of death or bodily injury rises as the voltage rises. I don't like working on 277 volts hot because it has the ability to blow off your hand or foot. Anything under that doesn't bother me though.

220 volt is more dangerous than 110 volt in view of electrical accident.

120 volts is slightly safer
An accidental "shock" doesn't hurt as much
120 is less efficient, and requires more copper (more expensive).
In the USA, appliances are limited to 15 amps, giving a maximum of 1800 watts, so the vacuums suck, or rather they don't suck...What I mean is, I hear the vacuums in Europe have more suction.
