Sorry for the delay.
Amanda Clarke-Peterson, you're welcome to participate.
The issue is that you see only the VISUAL part.
Everybody do not absolutely want to use a visual builder, I mostly never do it to build a Post and I had build thousand of Post on WordPress.
@Amanda Clarke-Peterson "You will have to go back to all of your pages and remove such shortcodes"
Maybe you do not know Shortcode Cleaner Lite > https://wordpress.org/plugins/shortcode-cleaner-lite/ . It's not perfect but do the job.
Make a test:
Build a post with Elementor and save it.
Go back to the classic mode.
Delete all text image and data left by Elementor and update your Post.
So now your post is blank.
Edit your Post again with Elementor ....
Tadata you will get back all text and data you have previously deleted in the classic mode.
In fact your post have been save twice in the database. Not very good for performance.
So good luck to clean your database of all the junk left by Elementor.
When you change a theme you always need to rebuild all your Pages/Posts where your have used one builder.
With Elementor like all other builders you can only get back some text or basic informations, all other data will be lost.
The only difference is that you do not have to clean the shortcodes because they are stored in the database in another table.
And once again I do not say Elementor is bad, I know how to use it very well, I have build entire website with it.
I just say by experience, it's a bad POST Builder.
Imagine you want to add a basic Before/After block in your Post.
With WPB you just need to add :
[cq_vc_beforeafter beforeimage="2626" afterimage="2625" autoslide="0"]
any where you want. You even do not have to turn all your post into a WPB format.
Your post will still be editable in the classic editor.
With Elementor you need to load the Visual Builder and by the way change your Post format.
This one will no more be editable in the classic editor without loosing all blocks data (beside text).
And if you remove Elementor, you will also lost the Before/After block like it will happen with WPB if you remove it.
So yes Elementor is a better VISUAL Builder, It's provide more features, it's a plus for a theme like re:hub but WPB for Post is a better builder.
Post and Page are very different, in a Post we need something simple, fast and easy to edit and Elementor do not provide that.
It's will be great to have both builders because they are very different and each provide a real plus if you know how and when use them.
And I do not say to clone all ELementor blocks into WPB. It's not needed and not possible, but at least update WPB blocks when a bug is found, and add new block
when it's possible.
