No doubt DA wins the race here.
I manage about 40 servers, most of the are DA.
cPanel is a great product, only it becomes heavy to run.
It has lots of unneeded features, and DA is quick to learn and adapt the better functionality.
Furthermore, I like the tree struct in DA much better. It is much easier to manage than of cPanel.
Pricewise,.. no questions, DA gives you much better ROI.
As for user functionality, I don't have a single user who said "Oh,. bring the other panel back". They all love the simple, yet very intuitive, effective and powerful navigation and functionality that DA has.

(oh... I don't have % in DA,...
