I don't know but I'm still using WordPress and have been for a long time. It has the features that I'm looking for and versus Wix, I feel like it offers more freedom in the terms of designing the site to 'match' your vision.
It's easy to use, fast, flexible, user-friendly, many plugins, ... I guess it really depends on your knowledge.
Out of the standard free ones, WordPress, Wix, Weebly and so on I'd really recommend WP. It's above the rest. Try it and see? if you feel too restricted you can just stop using it.
