I think beorg is fantastic and I poked around with it for a while before building org-web.
Ultimately I decided to build org-web anyway because I wanted something a bit closer to the metal, in a way. My impression of Beorg was that its bit higher level, whereas org-web provides some first class support for org features while still letting you edit the raw text if you'd like to.
To be clear, I think both styles have their advantages. org-web's style isn't better, its better for me.
