I don’t use the block editor here on Initial Charge. Instead, I write in Ulysses and publish to the site using Shortcuts. But I have other personal sites where I make use of the block editor and use it every single day at work.
And, boy, I’m sure glad I never used a page builder plugin on any of my sites. It seems like such a short-sighted publishing system that will eventually lead to pain points. If your goal can be accomplished with stock WordPress, it’s typically best to do so.
