That depends on the application you have in mind. Copper is 'best' for conducting

electric current from place to place without loss. Aluminum is 'best' for keeping cost of installations down or where weight of the conductor is a factor. A larger conductor size has to be used when using aluminum wire to carry the same current as a copper wire.

Aluminum also has some issues backing out of connectors so its important to make sure the connectors are tight. The current is actually carried on the surface of the conductor, which is why stranded wire is better than solid wire, more surface area, but more expensive. Hence aluminum has been substituted for copper. Some applications will use steel wire and "flash coat" the steel wire with copper, so the surface is copper the base is steel.

Are aluminum cans coins glass or copper wire are good electrical conductors?

Copper wire is the best, glass is the worst. Coins are not bad, aluminium cans are OK for small amounts of current. Modern steel coins are worse than the old coins with copper in them.

Why is copper wire used in house wiring?

Copper is used for most wiring because it is the best conductor of electricity (after silver), so is used in house wiring. However copper is heavy (dense) and for overhead power lines aluminium is the preferred material, to simplify the design of pylons.
