I'am new to angularfire2, the only difference I see from the two is in when Retrieving data as lists
you can query items, on the other hand Retrieving data as objects you cannot query.
Most of the snippets / sample projects I found on github related to angularfire2 uses lists and not objects, Really confused between these two. How to choose between lists and objects and what are the scenarios / use cases in which I should use objects rather than lists or it is only as simple as if I need to query something I use lists.
