Copper by a long ways over salt water.
Salt water is a lot more conductive than plain tap water (depending on where
you are).
Distilled water is basically an insulator

Some data from the "rubber handbook" (Handbook of Chemistry and Physics,
published by Chemical Rubber Company)..
condosity (T) is the molar concentration of a NaCl (table salt) solution
with the same conductivity.

Cupric Sulfate - 10% (anhydrous) solution in water, 0.694 molar,32.2
mmho/cm, condosity = 0.371
Magnesium Sulfate - 10%(anhydrous), 0.917 M, 42.7 mmho/cm, T = 0.506
Sodium Chloride - 10% - 1.832 M, 126 mmho/cm, T = 1.832 (of course)
Sodium Chloride  - 5% - 70.1 mmho/cm
Sodium Chloride - 20% - 204 mmho/cm
Sulfuric Acid - 5% - 0.526 M- 211 mmho/cm - T = 4.25

Copper = 1.7 microohm cm = 5.9E5 mho/cm = 5.9E8 mmho/cm ...

Note that conductivity is NOT a linear function of salt concentration...
