I think that is normally a good rule of thumb, especially when first party has a track record of accomplishment. It's one that I embrace. I am trying to stick with the original editor and find it increasingly hard as all of the design elements are now requiring Gutenberg. To be clear, I am not advocating for another page builder over Gutenberg, just not embracing Gutenberg because it embeds semantic elements in comments and if and when I need to migrate off of WordPress I don't want to be stuck. I have been using WordPress for 18 years, which is a long time for any technology platform. I don't have plans to migrate but I don't want to foreclose any options.
