Advantage of 220: Less voltage loss in the circuitry. Thus more of the

heating the wiring.

Tell you what: why don't you calculate exactly how much difference that
makes,
and get back to us with a monthly cost delta. Hint: not as much as you
think.

Disadvantage of 220: Costs lots to install in old work. But only an
electrician would know how much more (depends on whatever else needs to be
done at the very least..

Pfffffft. The additional labor to install a 240V circuit, as compared to a
120V circuit, is negligible. Certainly doesn't cost "lots".
Once upon a time, I wanted to install an electric oven in my kitchen which
needed a 60 amp circuit. The existing oven only needed a 40 amp circuit,
and that
was what was in the house. So, I called an electrcian to get an idea. He
quoted a very high price because he would need to replace the wiring. It is
the labor
involved in old work that runs the cost up. The cost of the wiring, etc.,
is almost incidental. I am talking about making changes to an existing
structure.
It certainly would not cost me very much to install a 240v circuit in my
garage because there is already a 240v line inside the wall.
