If you plan to go with hybrid app model, you rely on HTML/JavaScript technology, whose  home  is  web apps. So if the main reason to go with hybrid model is to be multi-platform with single code base, why not to support web apps too (together with hybrid app) ?

Web apps would have some limitations against hybrid apps,  but would be available truly anywhere.

So it is not one (web app) over other (hybrid app), rather I look on (HTML/JS)  web apps as core (and common, shared) minimum  that can be reused for hybrid apps.
