Among Molarity and Molality ,Molality is more preffered as Molarity is defined as no. of moles of solute present in 1Litre of solution.Now ,we know that Volume changes with temperature..Therefore, Molarity becomes temperature dependent.
Whereas , Molality is defined as no. of Moles of Solute present in 1Kg of solvent, now mass doesnot change with temperature,therefore, Molality is temperature independent and thus more preffered.
