  1]Steam (superheated) has all properties of a gas with reference to heat transfer.Additionally, when condensed it is easy to handle it in liquid form.It is available in all parts of world.As pointed by you,cycling the same fluid in two forms i.e.gaseous and liquid is possible in case of water.
  2] Freely available gases in nature are scarce.It is also impracticable(non-economical) to generate desired gases for heat transfer in a cycle. Moreover,leakages in the system/ cycle makes it difficult to make-up.
  3]Gases used in power generation mostly are heat source.i.e.combustible gases like methane.But major heat carrier media is air a natural freely available substance.
