Chris O'Brien's blog: Blending publishing/collaboration functionality in SharePoint: "Use of Content Editor web parts vs publishing RichHtmlField controls

Most folks in WCM development know there is an overlap in functionality provided by the Content Editor web part and the RichHtmlField control in the Microsoft.SharePoint.Publishing.WebControls namespace, i.e. they can both be used to enter page content such as text/images. However it's important to consider the differences - the RichHtmlField control stores it's content in a column of the list item for the page, whereas the CEWP is a web part and thus stores content in the web part storage architecture. This is important, since if deployment to a different environment is in your project plan or ongoing architecture, things will likely be simpler if you use the field control, since this content will then travel with the page properly.

Additionally, there are some URL fix-up issues with using the CEWP across different environments, as documented in the HawaiianAir.com write up.

In summary, I'd recommend considering the CEWP as a means of entering content in non-publishing SharePoint sites only."
