Blog, forum, online store (not marketplace, and the usual in several categories, basket and product card) better to do on the box... if the goal is not to learn to program — saves time, lots of ready-made solutions
Individual services (for example, a complaint for housing with reference to geo services for subscriptions to some services for mobile apps, some sites with non-standard and not particularly popular functionality) to do better on frameworks...
Portfolio website and business card done where it is more convenient (it may be that the frame is faster and Vice versa)
A lot BUT if the business creates a solution, there can be porridge of CMS+frame, and pure frameworks

The speed of the code execution framework.
The speed of website creation - CMS.
PS: it is not clear only one thing: how could such a question?)

If the functionality is insufficient on any CMS better write to her, or well, or when there is no such CMS that suits you. If you write frameworks is best for safety (of course it is possible still to debate) as others do not know your code. And functionality can do what you want. It all depends on your knowledge.

There is a knurled road and range ready machines, known for outstanding functionality, having the declared characteristics, allowing for a certain tuning.
If satisfied, select one of them.
