Like with most questions like this, the tl;dr is: It depends.
The correct navigational pattern is largely contingent upon three things:
- App structure (IA)
- Leaf page functionality (IxD)
- Desire to enforce prioritization by the product team (Organizational)
If your app is structured such that you can support fewer than 5 first-tier leaf pages, a tabbed approach is great. If there are additional pages that aren't contained in a core user flow, it can make sense to include additional functionality in the ☰ menu. These include:
- account information (eg. sign in/out, add user, etc.)
- outbound links (eg. help, feedback, bug report, etc.)
- folders and labels
Leaf page functionality
If leaf pages are sufficiently differentiated from one another but equal in hierarchy and priority, tabs is a pretty solid mechanism for navigation. Examples of this include:
- stream types (eg. YouTube's Home, Trending, Subscriptions, and Account)
- navigational patterns (eg. browsing per your example)
- content types and interaction patterns (eg. Google Maps direction types)
Desire to enforce prioritization by the product team
This is less about the discipline of design and more about its practice. Product teams have ever-evolving requirements, and as a result, the product/service can become bloated and unfocused. Choosing a fixed number of core user tasks and placing them in tabs helps design teams push back against product creating a junk drawer filled with long-tail functionality and enables the team as a whole to spend more design and development time on core functionality.
Try to avoid user tabs as a sorting or filtering mechanism. In your G+ example:
there are states in which users have top and bottom tabs, and the top tabs serve as filters for content in "Collections." The content within the "Featured," "Following," and "Yours," tabs is the homogenous. This is a strong anti-pattern for tabs. There are much better filtering mechanisms.
