In my opinion both of the control panels are good. For me a good hosting control panel is a panel that allows you to do EVERYTHING that you'll ever need from your shared hosting.
But:
Godaddy's control panel is very slow, without any reason for that. It's also not as advanced as the Cpanel.
If we're looking for something very advanced, Kloxo and webmin are good examples.
In fact, the Cpanel has became a standard for what a hosting control panel should looks like. It's easy to use, fast and reliable. It's a proven solution for both advanced and beginner users, with very nice design and well structured menus.
So, in my opinion, if the hosting plans and the prices are equal (this includes the uptime and the support) , select the one with the Cpanel.
Also, you could try the Godaddy control panel (and the hosting) - just sign up for a free hosting (you could sign up for a free hosting account with godaddy only if your domain is registered with godaddy). The free hosting is almost the same as the paid economic plan, but have ads.
There are a lot of websites that provides a free Cpanel hosting - you could sign up with one of them and test it.
