Three channels, each with its own walkthrough. They deliver the same schema and report the same crawler traffic, and they run together happily.
Coverage is the real difference. A worker at Cloudflare's edge sees every request that reaches your domain. A plugin or a module runs inside your application, so anything a full-page cache answers never reaches it - that is partial coverage by construction, and we will not quote it as a total.

This asks one question - did the code on a domain reach us - and answers for that domain only. It names the account it answered for, because a channel registers under the account that owns the API key it was given, which is not always the one you are signed in as.
