I just tried Wix the other day to make a landing page for and Android app I made and I have to say it's very preferable to WordPress for people who don't know web development.
It's also preferable for people who don't know how to manage a server and/or don't want to keep up with updates and whatnot.
The free templates are also way better!
Yeah, WIX is good but for me as a developer i prefer wordpress for those who don't know how to code, because it help them working and managing there websites
