I have yet to meet a client asking for Gutenberg. The theme I use had had a page builder now that works and requires about 5 mins training. It does everything Guts does and more. So why? Its also a paid supported plugin, if it breaks, which it never has on hundreds of sites it has support via the theme and the plugin devs. So this cant be overlooked, where do you go when Gutenberg is not working in a real world scenario. I cant trust this plugin, I cant recommend it and frankly I cant use it. I have built sites for decades, its one of the oddest and silly HTML editors I have ever seen. I still cant wrap my head around every paragraph being a block.
