Not so good experience, shouldn’t be default editor

So because of that notice on all my sites to try out gutenberg, I decided to give it a try. I created a new post and copy pasted one of my old blog post and result was horrible.
It deleted images which were in between a numbered list when I tried to add the image manually it was not possible as it was breaking numbers and design. User experience is so bad that I was not able to understand how to achieve that.
I tried other blocks too but it was not why we use WordPress, we should focus on content instead of spending more and more time on fixing layouts and stuff. If someone wants to create a layout there are many free plugins available, and they are so much better in terms of usability and they are well tested.

I think instead of making this plugin default they should make it opt-in like –
1) give user option to choose the editor while installing WordPress
2) Easy switch between visual editor – gutenberg – code editor (I think it is available currently while switching to gutenburg from classic editor it creates classic editor block)

I understand developers have spent so much time on this project but you should understand what people actually want in wordpress instead of forcing it, you can see there are so many bad reviews everywhere.
