Snap Mediaworks is much more robust and requires a significantly less overall investment from you.
Let me explain it this way: Using those BIY services is like spending your time and money remodeling your rented apartment. At the end of the lease you own nothing.
With Snap Mediaworks our professionals set up your site quickly. You then add the content to the site with our site management tools. At the end of your initial contractual period you will own the license to your web site.
Our service requires no huge upfront time investment and we offer ownership. That's the difference.
