Update - how to disable Gutenberg in WP 5.0 with a simple filter:

add_filter( 'use_block_editor_for_post_type', '__return_false' );

Put the code in your theme's functions file, or in a plugin... things slowly are starting to make sense again... Personally I will be using Gutenberg, the Meta boxes are the only issues left for me which the devs are working on as we speak I guess ...
