Does a lower profile tow better? NOT a mileage Question

Our travel trailer (BigFoot) had radius top corners all around similar to an Airstream and was also a low profile trailer. It towed very nicely and super stable but the only other thing I had to compare it to was a very low profile Coleman pop-up. That thing towed just OK except when the water tank was filled and then it swayed terribly. There are other tradeoffs with low profile. Any one over 6'-2" should probably cross BigFoot off their consideration list.
