From what I have seen, many C's do not come with levelers, that are controlled from the driver's seat. Also from my own experience, it is a lot harder for the passenger to get to the back of the coach while driving down the road. She likes to get up and grab something to eat or drink or to use the toilet while we are on a smooth straight highway.
The view out the windshield is much better in the A and the higher driving position is better to keep an eye on other traffic. To each is own. Just drive both and decide what works the best for you.
