Wizards can kick-start features. They can also obfuscate your code, and are anti-YAGNI.
On balance, do you think Wizards are more useful or more harmful?
They are more useful than harmful if and only if you understand the code they generate. Only after you mastered the problem the wizard is trying to solve they are really useful. Otherwise you'll hit walls later in the project, because the generated code will need modifications at some point.
"The Law of Leaky Abstractions" really nails it on the head.
