Using CKEditor in #CraftCMS v5+ is - at times - a very good author experience†. However, without the relationships that are stored when using the 'traditional' Matrix-based approach feels like you may well be losing the thing that made the CMS such a great platform to work with. This may only be realised in the long term as your website evolves.
