IMHO, Gutenberg is still in development, and there are a lot of things need to be improved. I believe that Gutenberg developers will make it most convenient like we use TinyMCE before. Don't try to compare the Gutenberg beta vs. current editor then vote it 1 star. Let's send your opinion, or things need to be changed to Gutenberg developers for them to improve it. And I hope criticisms or 1-star ratings do not make the Gutenberg developers frustrated.
