In reply to Álvaro.

I haven't tested all of those, but I can say that Gutenberg Hub's templates will be pretty similar in nature. They are one-click to copy and you just paste directly into the editor. Simple.

The big difference will be that they will be available through an interface directly in the editor. So, it cuts out a step.

One thing I have seen mentioned is the need for a sort of official "block pattern directory" for users. Perhaps that is something we may see at some point down the line. Having 1,000s of patterns in the editor would probably be cumbersome. But, connecting that to an API with search via WordPress.org could open up some possibilities.
