There is a big difference between a web builder and a web designer. A web builder is simply taking modules, pre-made graphics and statures and arranging them in a way they find to be pleasing for their needs. This is a good way to build sites with limited experience, but it provides limited results too.

Then you have web designers and they create websites from scratch with a look, a structure and graphical features that are completely original. This is definitely the best way to create a websites because it provides unlimited creativity.
