This is a pre-built solution for a single domain. If you want to get a single web site working and don't want to use Dreamweaver or customize a whole lot, then the solution is the way to go.
If you want deep customization, but like the idea of a head start, maybe both the tools and the solution are a good investment.
If you like to design your own database and have a deep knowledge of Dreamweaver and Database design, then you should probably just get our tools and do it yourself.
The difference is the same as the difference between a pre-built house and all of the tools and materials you need to create as many houses as you want. If you just need one house and you like the prebuilt design you can go with it. If you like the pre built design and you want to create additions, then you should get both. If you want everything custom, then the tools are all you would need.
