I treat memory as a resource too precious to be left to the mercy of programmers. In any application, a good garbage collector can be more efficient than malloc/free or new/delete.
?? I admit the last time I really coded in Obj-C was for NeXTSTEP. But back then init ultimately called malloc, and release ultimately called free. In any case, yes, a good GC can be faster as it takes advantage of cache effects.
