predicting entropy

4G.3 Which would you expect to have a higher molar entropy at T=0, single crystals of BF3 or COF2? Why?
The answer given in the solutions manual says that COF2 is the right answer because it is asymmetrical, with an O and two F instead of three F. I also said it was COF2, but I said that it was because this molecule had less electronegativity difference between its atoms to influence the molecular orientation away from randomness. Is this correct as well? If so, which factor, polarity or asymmetry, takes precedence in answering this sort of question, and why?
