The best one is UltimateWB. I use it for all my websites. You can build any type of website with it. It has lots of built-in apps, including for photo galleries/slideshows, social networking, and e-commerce. It’s very customizable and flexible. You can get your web hosting there too, or download the software and install on another server.
