Im struggling to wrap my head around which or rather how to construct menus for content heavy and simplistic (brochure) sites. I have a friend who recommends I use books for both. Only use new content types for pages that function differently or do not have the same fields. From a users (editor role) point of view it works really well, since there is way less clutter (not seeing all the primary nav items and subitems) when trying to add a new page to your site structure, and it works really well by using a book menu block per page.
I am wondering how others do it. I have found that true to my friends advice this is very simple to do, works well, is straight forward and is part of a default install - no mods needed.
How do others do it ?
As an example, here are two pages with different submenus per section.
