I've used most of them: FusionBuilder, WPBakery/Visual Composer, Elementor. I honestly despise these page editors. They are so incredibly slow, and the markup they produce is indecipherable.
I've been pretty happy with Gutenberg. It has some pain points - notably around block recovery - but it produces sane HTML, its CSS payload is minimal, and there's no frontend JS at all (at least in the default blocks).
You don't get the millions of features of those other editors, but it's those same features that make them slow and cumbersome. I think Gutenberg strikes a good balance. It's the first page editor I don't hate.
