with interfaces, because you must do a typecast every time.
Compare
Function GetPluginInterface : ISOmeThing;
begin
X:=MyPluginObjectXYZ.Create;
Result:=X as ISomething;
end;
This is then a weakness in the language. Because MyPluginObjectXYZ
implements ISOmeThing and the compiler nows that, you should be able to
write just
Result := MyPluginObjectXYZ.Create;
Weakness ? I do this all the time in Delphi. No need for as

With
Function GetPluginInterface : TSomeClass;
begin
Result:=MyPluginObjectXYZ.Create;
end;
