Don't quote me on this, but I almost positive Patrice is right about not being able to design your own blocks on Design Wizard. And I think you only get like 200 or so blocks in its library...seems like a lot, but it might be a lot of the same old blocks we've seen over and over. Not saying its a bad thing, but if you're looking for something where you can expand your creativity as much as possible and play around with a lot of things, I'd probably go with EQ6. And people say some very positive things about that program so it looks like it'd be worth the buy even if you don't use every little thing on it.
