I hate to start this off this way but this comment makes me feel like you're either a very novice WP user or simply a designer that likes to advertise themselves as a dev but doesn't actually do a lot of coding. Divi and Visual Composer are both absolute messes from every aspect except for ease of use and they're incredibly bloated even for simple page layouts. Everything ends up as an inline style, the actual load time for pages is astronomical, and making any kind of theme changes are impossibly inconsistent because these page builders inextricably link all styles to the HTML instead of in proper CSS where they belong.
Gutenberg, on the other hand, while not perfect, is several times better than these systems, in my opinion. There's still some messiness to it but it's much easier to set up a theme for a client and have comfort that, when you come back to edit something for them, they haven't borked it all to hell requiring you to dig through a slow and clunky interface just to reset a font-color.
