It is not as sophisticated as webflow.
I have used both, I find editor x is much faster for development but in terms of getting into the nitty gritty, I am someone who loves to use obscure CSS effects in my designs, with Editor X that is a huge pain.
For example, you cant use inner element shadows or even text shadows, no gradients, you cant even have a sticky element in a no overflow section.
The biggest reason to use editor x over webflow for me is the client experience and extra perks, for example the shopping and members account is much better in editor x because its using the wix library that has already been working on that stuff for many years before webflow.
But if you want full control over your design work then go with webflow, designing on editor x feeling like your fighting against the editor unless the website is very barebones simple.
