The heat transfer coefficient of condensing steam (in case of saturated steam) is more higher than super heated steam. It's around ten times more, ranging between 8000 to 10000 kcal/m2/h/degree Celsius against 1000 unit of superheated steam.

Superheated steam has low heat transfer coefficient as compared to saturated steam that's why we prefer saturated steam over super-heated steam.
