I recently finished shooting a video course for Phlex and I found that naming the Turbo Stream section at https://beautifulruby.com/phlex#unit-5 was the most challenging because of Turbo Streams and Turbo Broadcasts.
My recommendation: Turbo Drive & Pagemorphs are what most people should use for most problems. Drive reduces flickering between page loads and Pagemorphs list to channels on the server to reload the page if something changed.
I think Turbo would benefit from positioning itself more closely to Rails and simplifying the terminology. If you look at the https://hotwired.dev website, you won’t find Rails and you’ll find a bunch of words like Stimulus, Drive, Streams, Broadcast, etc. The docs aren’t entirely coherent either.
