I've elaborated on this in another thread, but I can't put hand-drawn animation over CGI or vice-versa, because I've seen good and bad examples of both. I've seen as many lackluster hand-drawn cartoons as CGI-rendered ones, so I really couldn't say that one animation style is innately superior or inferior to another. The key to a good cartoon to me isn't what style it's it's rendered in, but the quality of the story, writing and characters. CGI is just another way to tell a story, IMO.
