Clean, performant, perfect!

I think the bad reviews are from people who don’t know how to use it or try using Full Site Editing. The best approach is to keep Gutenberg for page/post content using blocks and also use theme.json to define design tokens that can be reused in your theme and blocks for consistency. You can keep using PHP for everything else. It’s so much better than Elementor or the horrific mess that Divi is.
