 Not really better, but certainly safer.  Electric heaters are all 100%
efficient.  Every watt you shove into the heating wires is turned into
heat.  There's no way to improve on 100% efficiency.

Wrong: There's no *simple* way to improve on 100% efficiency.  As soon as you change your definition of "efficiency", there might be additional improvements.
Examples include

(you gain additional heat by emitting liquid rather then gaseous H2O)
or
<https://en.wikipedia.org/wiki/Heat_pump>
(cooling the outside brings you additional warmth inside).
