The former will be slower, since it will create a list containing all the models and then yield them one at a time, whereas the latter will just use the list directly. If you want a generator then you should use QuerySet.iterator() instead.

No. Other than the fact that it’s more verbose, redundant, and not particularly useful (in the context of the generator you provided).
When you do Item.objects.all() in a for, they’re iterated using iterator with query caching (source). If you don’t want the results to be cached, use iterator() like Ignacio recommends.
