I've only used 2 Wordpress-based drag and drop editors. Semplice and Visual Composer. I wouldn't characterize either as dumpster fires. Semplice is easier to learn and feels like editing in Medium but Visual Composer might have more features.
I've seen some custom editors that are terrible (as you mentioned). But these 2 are built by top teams that keep the products updated.
