Arc and autorelease

Without Arc, this:

NSString *s = [ [ NSString alloc ] initWithFormat: ...];
[ someCollection addObject: s ];
[ s release ];

is clearly more efficient (because not using autoreleasepools) than:

NSString *s = [ NSString stringWithFormat: ...];
[ someCollection addObject: s ];

But what about Arc?
Is the compiler clever enough to make both versions equally efficient?
Or should one still avoid using the convenience method stringWithFormat: ?


Kind regards,

Gerriet.
