I’ve easily built hundreds of WP sites and Gutenberg makes me sad. Anyone raving about the block editor has clearly never used one of WP’s paid page builder plugins like Beaver Builder and Elementor, they’re in a whole different league. You of course can continue using these plugins, but the absolute chasm in quality separating these plugins and Gutenberg highlights Automattic doesn’t have the technical or design kno…
I've been pretty happy with Gutenberg. It has some pain points - notably around block recovery - but it produces sane HTML, its CSS payload is minimal, and there's no frontend JS at all (at least in the default blocks).
You don't get the millions of features of those other editors, but it's those same features that make them slow and cumbersome. I think Gutenberg strikes a good balance. It's the first page editor I don't hate.
