For single-engine piston aircraft (that would be planes with top
speeds around 200-300 mph) a three-blade prop produces more force
which means a faster climb rate. But, at the expense of more
resistance and therefore a less efficient cruise.

But-- there is fast airflow against the prop. Which you don't have
with a ceiling fan. Nor is the ceiling fan producing anywhere near
the thrust of an aircraft prop.

The point being, not a good comparison between the two.

See which fans blow more air on you, then look at the electricity
consumption of each...
