Knowing how to use IDL will give a better quality render than knowing how to use "regular" lights.

Using anything without knowing what you're doing compared to doing something you know... well, we all know how that usually ends.

But in truth, IDL is too simple for most people's habits. They're used to killing the scene with lights; that's probably the biggest reason why IDL renders look bad for them. With IDL, I almost never use more than two lights. Often, one.
