Choosing a CMS: EPiServer vs Orchard vs SiteCore vs Umbraco?

I can only comment mainly on Sitecore and a bit on Umbraco from my knowledge of others using it.

Of the ones you mention above, I have only used Umbraco and Sitecore to build with and am certified in both. I like the way they allow me to build systems that really work well for my customers. They both have a feel that they simply give you building blocks to create your masterpiece instead of "modules" of functionality plugged in that give you a blog, forum, etc. They make it really easy to share content throughout the site and create really nice admin experiences.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
