I don't have as many hours in SolidWorks but for me, trying to navigate without a 3d mouse feels like riding a bike with square tires. I could manage to do it but why. At the end of the day though it's a preference. Likewise I have to murder the x and y axis on it for things to click in my head, which is another preference. I suppose growing up as a gamer may have something to do with that. I don't want to move/rotate the object, I want to move/rotate the camera..
