ASP.Net CMS recommendation, Orchard, Sitefinity, Umbraco or N2? [closed]

Orchard is being developed by the Microsoft team and being pushed by Scrott Guthrie, Scott Hanselman and others, so support should be no problem at this point. Orchard is being build on top of the new features of ASP.Net MVC 3 and so is state of the art. My vote would be on Orchard.

I have only tryed Umbraco, its easy to use for the customer, developer and there is a very good split between code and content so the customer will never have to see eny code.

Because it wasn't mentioned here, I'd like to advocate for N2CMS. Though its documentation sometimes leaves a little to be desired, once you're up to speed, developing for it is like a fresh breath of air compared to some other CMS's. It's extensibility is far beyond what you would expect, though you sometimes have to dig into ILSpy to find the gems.

Support on the N2CMS forum is really up to par, thumbs up for the developer(s). It has also been around for some time right now, so you can call it pretty mature.

Upside - wich might also be a downside when trying to keep up - is that it's under pretty active development, meaning important bugs get smashed quite efficiently.

I must admit I have little experience with Orchard (looks like it's really a match on several aspects), and because of MS supporting it more or less, I think Orchard might win the game by sheer exposure :)
