This is definitely a tough one. Your goals will really have a massive impact on which platform ultimately will work best. If you are building a basic blogging system, we would definitely recommend Webflow and converting the template to something like ghost. Ghost is a beautiful platform you can self host that is really nice and easy to blog from. Using something like Wordpress for this may become a chore and distract from the fun of blogging.
However, if you are wanting to build something like trainsaferesources.com (a full LMS system, with eCommerce and user management roles_ we'd be using Wordpress because there are a ton of ready to go plugins to build it on. Whereas with Webflow, you simply wouldn't be able to put something like that together because the platform has limitations.
