I have used Wix, Squarespace, and WordPress. Maybe if Divi wasn't so easy to use, powerful, and backed by the best support in the world, another "builder" CMS would work. But since Divi turns WordPress into a 110% customizable beautiful interface, I can't imagine ever using Wix or Squarespace ever again. Squarespace has nice templates but the ability to work with them is absolutely terrible. Wix does better than Squarespace for functionality, but using Divi has been an absolute dream. I run a copywriting and website design business. Could not do it without Divi + Divi support. 6 stars out of 5. Love.
