Generally speaking, if you want to provide a list of things, just return a list. People can assign it to an array and loop through it, access a particular element by index, etc.

The exceptions would be where there are so many list items or the items are so big, that they would use too much memory to store in an array, so accessing them one by one is better; or if generating each item is relatively expensive (in terms of time, CPU, network activity, etc) so if you can avoid fetching the entire list, that is preferable. In these cases use an iterator instead.
