What is more efficient: Rec or Cont?

type Rec new Limited_Controlled with
   record
      Str: access String;
   end record;

--
-- Code to automatically deallocate Str when Rec is finalized
--

or

type Cont is new (String);

(Note: in the real code it may be Interfaces.C.char_array instead of 
String.)

Should be instead:

type Cont is new Containers.Indefinite_Holders(String);

Cont, because it makes more efficient use of the developer(s). Anything else is 
only an issue if using Cont is preventing the system from meeting its timing 
requirements.
