The reason the US uses 120 is it is far less likely to kill you outright.
Higher voltage is what precipitates unusual path choices in semi conductors
and insulators which is technically what homo-sapiens are to an electron.
Most 120V fatalities are from the sudden impact upon the
floor/stove/ladder/couch/cat after falling.
If the house is wired correctly the toaster in the bath tub will do nothing
to the participants, the current will go down the drain literally.
Hollywierd, and in particular, CSI is very bad about this fact.
Hi V efficiency really only gets useful on long runs like from the nuke to
your city/town/commode/etc.
As one who has tasted 120, 220, and 480 as well as a few 80K ignition coils
and one mega K electric torpedo ray(as in fish, yes they really do exist),
the 120 tastes much better.

It's not a place to discuss this matter but the true reason why US uses
110V is much more simpler - we/you do that because Edison designed his
systems to produce and use 110V (going to higher voltage was very costly
back then). Later on as the network grew up it became more and more
harder to switch and finally people just dropped this idea because of
the cost.

Edison also used DC (he thought AC was too dangerous), Tesla won that
fight!! Our present grid would not work with DC current, and until about
15 to 20 years ago the clocks would not have kept time (at least at an
affordable price).
