Cables are different heights and if you have to deal with water loss/gain it also affects it. (Florida provides us with some entertaining weather) Rope lengths and speeds can vary as well.

I always feel like i ride way harder at my home cable, its just the right vibe. I am not sure if others are like that. On that note, I am biased to clockwise
