I choose Other.
I roll my own web site(s). The host is SkyLink and they are inexpensive and utterly reliable. There are many other excellent hosts as well. SkyLink also will register domain names. While not being unique in anyway, you also get an email address that uses your web site name. In some areas of commercial photography this is a useful marketing tool as it differentiates you from people who just use gmail or some other generic mail address.
I use OS X and produce the web site(s) with Sandvox ($80). Obviously there myst be similar products for Windows platforms. At first I used a third-party photo gallery app (Juicebox LR Plug-ins) for their flexibility (e.g. automatically provide both mobile and tablet galleries) and polished look. Since LR 6, Adobe's web albums are just as good... if not better. Now there are numerous third-party web gallery LR plug-ins that support private viewing and image selection/e-commerce tools.
Besides a portfolio presence I also built minimalistic web sites for client photo delivery via ZIP files. This was a simple, bullet-proof way to offer private, in-line image delivery.
My programming skills are primitive. But in a previous life I managed SW developers. From them I learned to go slow and document everything I do regarding web-site/gallery production. That way when I want to make changes or additions, I don't have to re-learn everything.
Sandvox and other apps are compatible with customized code and there are third-party companies that sell Sandvox templates. But a truly unique professional photography presence where the look and user experience is precisely as you want it to be requires skills and experience in web coding. My view is it is more productive to spend time and money on other marketing activities than create or pay for custom coding.
I never marketed in the wedding/event space, but no doubt there are polished, professional turn-key solutions.
