I have no real opinion on the Classic Editor vs. the new Block Editor as far as how convenient they are to use. I'm not a blogger; I put together websites for clients. The issue for me is that I have no desire to convert dozens of existing client sites to using the Block Editor, and then to spend hours training them to use it. And I just did not need to be forced to learn what is basically entirely new software on top of all the other work I have. The Classic Editor was fine, and using a theme like Divi improves my WordPress experience 1000%. I just don't need this big hassle and massive extra work. There's so much more to what I do than which Editor I'm using. I'm trying to run a business :-)
