We can debate on here again.I'll have to look for that endless debate on here. I've never driven one. I drove an older one with paddle shifters but I know it wasn't the same. Just a normal automatic with paddles. It was horrible. I like the fact that just anyone can't drive the standard. And it's more fun to me although I know it's not as fast.
There are many differences of course. The DCT on the C8 will not let you lug for example. It will downshift when it has to regardless whether you are in auto or manual mode, but it will let you bounce off the rev limiter! It's sequential so you can't select a gear directly, but you can select neutral by pulling in both paddles. Your left foot will get bored, but now your left hand has something to do. With a DCT it is smart enough to know what you are doing and is (almost) always in the next gear waiting for you to pull the lever to switch clutches. So it's much faster than any human can shift with a stick and pedal.
I will admit one feels a little more in charge with a stick and pedal, but both can be fun.
