It is beloved by designers for giving them complete control of all output, and by content authors for enabling reusable, high-performing content.

ExpressionEngine separates your content from your design, enabling you to make small or large changes to your website with ease. Your content is stored in Channels, and your design is kept in Templates, both of which are entirely under your control. ExpressionEngine bends to your needs, not the other way around like many other CMSes.
