Hey Rod! In case it helps, I wanted to pass along this post talking about when it might make since to use the Gutenberg plugin itself:

It bums me out sometimes to see those reviews as often they are from people who likely wanted to try out the block editor and thought they could only do so through the plugin. Thankfully, each WordPress releases bundles stable features from the Gutenberg plugin releases:

I mention this as something to keep in mind as the Gutenberg plugin still does intentionally include experimental features in order to stabilize and test what's eventually included in Core releases.
