What is the most flexible .NET based CMS software

I am looking for a very flexible CMS. I want to use the CMS to create a comparison m开发者_开发百科atrix. I have tried wordpress but could not figure out how to create a comparison matrix. Do you guys know of a very flexible CMS to create this kind of content?

Umbraco is a very flexible, .NET based CMS.

In the old days DotNetNuke was a viable platform, but the underlying technology seems ancient compared to the new Orchard Project.

While it is still very early, I would expect this to be the defacto CMS for many people. It is just so architecturally robust and optimized to leverage the latest technologies in the .NET space.

DotNetNuke is by far the most popular. It has a large number of open-source extensions available too.
