Concrete5
Concrete 5 is a relatively newer CMS, but is gaining rapidly in terms of its user-base. An advantage of C5 is it’s simpler user interface when it comes to managing content on the back end. Additionally the C5 community is a more aggressively managed (think iTunes vs Android market place) resulting in better quality 3rd party products offered up in a more standardized streamlined format. A trade off is that being a more recent entrant to the space there are fewer 3rd party plugins to choose from. The Andesoft team has not only worked with several C5 deployments but are also contributors to the C5 community with their own plug-ins that address specific unmet needs.
