In Malaysia,

Assume
#1 = Gas
#2 = Induction
#3 = Radiant

Running cost (in order)
#1, Gas is still cheaper, because is subsidized by government.
#2, Induction is good, because the transfer of heat are very efficient
#3, Radiant, transfer of heat are slow.

Usability
#1, can use most of the cooking pots, woks, pans, clay
#2, you can only use anything with steel, Iron and flat surface.
  - But the market is getting more of pots and pans support induction. Even some claypot can support induction.
#3, Can use most of the pots, pans, clay as long is flat surface.

Efficient
#1, not so efficient
#2, is the best, boiling water is so much faster compare to gas or radiant.
#3, slow heat up. If your cooking time is short like fry egg, it waste lots of energy. Take time to heat up.
I personally still prefer gas, and 2nd choice is induction.
