So does that mean the premium web site building is the same as free

WHY NOT LOOK at what you have with the Free hosting/site

and the Premium Hosting plan there is a lot different with it

so are you saying that my site can look a lot better if I get the premium??

The differences are listed at http://www.bravenet.com/global/hosting_matrix.php

Your choice of editors are not one of the things that is different. You can struggle with the difficulties of the "easy builder", or use one of the many free or expensive programs available elsewhere.

The appearance of your site (apart from the free site advertising) will depend mostly on your skill, not your choice of hosting. But there are a number of things you can do on premium hosting that won't be possible with a free site.
