When I saw the headline I thought that the message was going to be to tailor your tech stack to the type of site. I was wrong. This looks to be a sales piece for their potential customers to convince them to use Gutenberg and not a page builder. There are some inaccuracies, like about Beaver Builder, but also they totally gloss over the need for custom development, which a page builder might not require. In any event, WebDevStudios is a large agency, so it is interesting to see what they are doing.
