I go by the first part of that description
You should only use this function when you do not know the fields which which will be appearing on a template…
and the part in bold of the second part
…or if you have a large amount of fields which you would prefer not to code independently.
Since I always know what fields will appear and I prefer to code them independently I don’t use the function. Also, most of the time I don’t want to use a simple loop to display the fields and I’ll likely just need to access the elements of the array instead of using get_field() where I’ll be using the value.
I might use this for a simple list of field content when the order it’s entered is the order I want to display it in.
