Choosing the right page builder is crucial for a WordPress site. Gutenberg, the default editor, is lightweight, fast, and uses a block-based system but lacks advanced design flexibility. Elementor, a drag-and-drop builder, offers extensive customization, templates, and motion effects but may slow down the site and requires a paid plan for advanced features. Gutenberg suits speed-focused users, while Elementor is ideal for detailed designs. The choice depends on your needs, budget, and expertise.
