I watched both a while ago, things could have changed. Inferno was positioned back then as some kind of a ressearch thing not suited for production. Preact pros was: - very small size (it's near 5kb Non-Gzipped without compatibility layer), perfect for lightweb mobile apps (Inferno was like 60kb, React 250kb) - has less gimmicks for porting from React and an optional compatibility layer to enable some of low-level React libs and components Preact has no synthetic event system wrapping, if you heavily relly on it then things could be rough.
