I was not a fan of the Block Editor at first. It was clunky and I usually didn't use the visual editor at all before that. I would hand code HTML and cut and paste into the post editor. But doing that made making posts a chore.

The Block editor makes adding posts so much more fun and it allowed me to use it as a visual editor so I know what the post will look like before I publish it.

The recent update allowing text and background colors for blocks really helped a lot.

I previously coded my own theme but Blocks allowed me to renovate the sites I maintain into a basic theme like Twenty Twenty and it looks good with less work for me in the long run.

My guess is if I was more into page design and CSS I would want more control than Blocks give you now. But for an intermediate hobbyist like myself I like Blocks
