Agreed. I'm building a site for a client right now and this time I decided to use Gutenberg cause the project is small and not too complex. Once I started to nest blocks, the weaknesses of Gutenberg began to show their ugly head. One of its main faults is the lack of visual clues that help you differentiate where one block begins and the other ends, so the task of selecting a specific column or a block inside a container becomes a challenge. This has been brought up many times on their GitHub with no positive outcome.
