This is less about React versus Vue and more about whether you're building a commentary on someone else's idea or actually creating something new. It pushes you toward first principles thinking when architecting features, with practical guidelines on when to add complexity (SQLite to Postgres at 10+ concurrent writers, monolith to services when teams can't share a codebase). The UI/UX section is equally opinionated: visible state, no layout shifts, undo at the data layer not just the interface. Use it when you're in the "what should we build" phase or reviewing designs that feel derivative. The framework comparison tables alone are worth keeping around.
