Everything is relative.
http://www.mindbranch.com/reports/pdfs/R2-708Sample.pdf
shows that lead has about 1/12th the conductivity of copper.
That is significant mainly in high amperage circuits. You could
compensate by making the lead conductor 12 times more massive than
a copper wire, but it certainly wouldn't be cost effective. For a typical
high impedance signal circuit the poorer conductivity of lead would not
be a factor.
