Webflow vs Wix vs Dreamweaver

Hey guys I recently started learning webflow. It feels great to be a part of the webflow community. I just need to know what is the core difference between Wix, webflow, and Dreamweaver.

My friend wants me to design a website and develop it. He says he has heard of wix. He has an idea of a real estate website and data is to be uploaded and updated constantly. So a CMS would be required. How shall I convince him not to go for Wix and go for webflow instead? How much shall I charge as a beginner?
