No, GCs collect reference cycles. Whereas a (strong) reference cycle in ARC in an operation repeated many times in a long-running server or something adds up.
Worse, sometimes, you don't even know if you're creating a leak. For example, I recently had to call, given two gesture recognisers a and b:
a.requireToFail(b)
A is a long-lived object. B goes away when the current view controller is popped. But not if A keeps a strong reference to it. Does it? Probably no one without access to the source code of UIGestureRecognizer knows!
