Are you using KnowledgeTree or SharePoint?

It has been awhile since I've considered using KnowledgeTree on the office intranet. I eventually decided that I needed to focus more on our content management system (we are now using Drupal) and consider implementing a document management system (DMS) at a later date. A recent Linux.com article on KnowledgeTree reminded me about the DMS that I almost forgot about.

These days, effective document management means accessibility from anywhere on the planet, electronic storage, reliable backup, and instant document modification updates. KnowledgeTree offers all that and more. It's available in several editions, including an open source community version (which we reviewed last year) that businesses can tailor to their individual needs.

You can install KnowledgeTree in-house on your company's server or use it as an online, hosted service. With it, you can create, edit, and store documents from Linux, Mac, and Windows computer. KnowledgeTreeLive, the hosted version, can be accessed from any computer with an Internet connection and a supported browser -- Firefox, Safari, or Internet Explorer.

I always promised myself that I would take a second look at KnowledgeTree sometime down the road. Unfortunately, at least for for KnowledgeTree, the regional office I'm under has started a move toward Microsoft's SharePoint. As I've written in the past, SharePoint is confusing system to describe and even Microsoft has a tough time explaining their product to potential customers. I initially thought SharePoint would be more of a CMS, Portal, and wiki but each time I've looked at SharePoint I'm realizing that it's greater strength may be in document management.

So I'm curious what advantages users of KnowledgeTree see in their DMS? I'm also curious what advantages users of SharePoint see in their server? Also, do we have some CMS Report visitors here that are former KnowledgeTree users now using SharePoint, as well as any former SharePoint users now using KnowledgeTree? If so, I especially want to hear your opinion of how these two systems compare when it comes to document management?
