I prefer SC because it is far more efficient to change geometry than DM in terms of number of clicks to complete a task.
The one area I found SC to be worse than DM is Parametric Design and the reason is DM has a history tree and SC did not. That means if you have a 100 mm long body with a hole at the 90 mm position, and a parameter on the length, you can set the length to 80 mm and the hole will disappear, but when you set the length back to 100 mm, the hole does not reappear. That does not happen in DM.
After I learned about this problem, I read that SC added optional history, but I have not learned how to use that yet.
