In reply to Jascha Brinkmann.

+1, I can speak to my experiences using 3 of the most popular editors: Divi, Visual composer and site origin page builder.

Divi is really good and pretty fast but the ui is so far away from native wp its really jarring.

Visual composer is pretty slow, super complicated and once again the ui is pretty far from native.

Page builder is really good, reasonable speed and pretty close to native. The love editor is pretty fast too. The only downside is when you have finished on the live editor it takes you back to the backebd. If Gutenberg could work like this but be faster (instant preview) i couldnt see barely any advantage to wix, squarespace etc

The market that those website builders capture is the startup low cost business, but i feel like they have raised the bar where every user now thinks "I should be able to edit text live". Certainly in the past 2 years i have seen that go from a bonus to an expectation.
