Crystallization is better than evaporation in mainly two ways, :
1. in evaporation, the solution needs to be at the boiling point of the solvent, the whole time. This may degrade the solute.
2. in crystallization, the crystals automatically throw away impurities to arrange themselves in a regular manner. Therefore, the degree of purity is higher than the solute left after evaporation.
