I want to make this clear: I am NOT promoting any other product.
There has been a big debate in the Webflow Forums about Editor X. Experienced designers have weighed in their opinion about Editor X. Have a look at one of the posts from their forum where a Webflow Community Specialist did some tests on Editor X: https://forum.webflow.com/t/webflow-vs-editorx-vs-code-editor/123664
As per the Google Lighthouse results, Editor X faired poorly. It was a 93 score for Webflow site and only 26 for Editor X, whilst other products like Superhi scored 98. @Sebi Vidret, Product Manager Why is the performance on Editor X sites so poor? This result is embarrassing for Editor X (I feel second hand embarrassment as I use Editor X while Webflow specialists expose the weaknesses.)
Another designer said this:
In terms of Editor X, it’s great that there is direct competition and that will only benefit us as customers, but Wix has got some catching up to do before I’d even consider using it with any of my clients. They have some cool features and things I’d like to see adopted by Webflow, but I personally find the UI/UX lacking. The “loosey-goosey” nature of their visual editor is great for beginners, but I find it’s less predictable than the more traditional development style in Webflow.
Here's another one:
Wix (and Squarespace, etc) is not for making professional websites.
I tried Editor X last week and it was a terrible experience. It is quite impossible to have 100% pixel-perfect control on Editor X. The page will become hard organized as it does not respect HTML hierarchy. The CMS is so weak as well.
I think Editor X is a bad idea right from the beginning. It is trying to work like Figma / XD / Sketch, and something between Wix and Webflow. I don’t think it will become a good product even in a long run.
For us, Webflow is the only “low-code” option for serious clients.
After doing some research, I found the reasons why people say Webflow is way better.
When is Editor X planning to improve site performance, build a stronger CMS, allow us to add custom CSS and edit the CSS Stylesheet and add custom HTML? I understand Wix is all about making things simple and keeping everything in-house but allowing us to export nice clean symantic code from Editor X and allowing us to host it elsewhere would be game changing. Apparently, other professionals say Editor X site code is VERY bloated causing bad performing sites. This is where Webflow succeeds as they allow people to export code. This opens the doors for large companies to use the platform. Large companies could design their site with Editor X and then export the site so they can host it and plug it in perfectly to their sophisticated back-end. (Velo is very basic and limiting so its not ideal for larger business).
I'm a fairly new designer and I love Editor X, but doing research reveals Webflow is more robust to use if i want to scale my web design career and earn lots of money and get big clients.
