You partly wrote it, it's fast/predictable but larger (larger because ram is 
dedicated to a pool)
against slower/fragmentable but potentially smaller (smaller because ram can be 
used for everything
as long as you have enough).

There's no single answer for this. You have to know your requirements.

The big downside of a heap is that it can get fragmented, and without an MMU, 
we don't have the
possibility to defragment it.
