I wrote the comment you cited :) IdentityServer certainly has better documentation for its extension points at the moment, but the tradeoff is you have to build everything yourself. Keycloak comes with a built in admin UI, account management UI, TOTP and WebAuthN support, the list goes on. You have to go out of your way to build these or search for a mismash of plugins for IdenityServer to get everything Keycloak provides out of the box. And while the extension points of Keycloak aren't super well documented, literally all of them are in a dedicated Maven module [0] making it easy to just browse the code.
