|How To Switch Between WordPress Classic Editor And Gutenberg
Good news! You can have your cake and eat it too.

You'll now be able to use either editor for any page just by switching back and forth if you need to.
But here's a little warning. Don't fall in back love with the Classic Editor. It is scheduled to be phased out and not supported by WP in 2022.
