Let's turn to http://www.erlang.org/doc/man/proplists.html to find out what a proplist is: "Property lists are ordinary lists containing entries in the form of either tuples, whose first elements are keys used for lookup and insertion, or atoms, which work as shorthand for tuples {Atom, true}." Sounds pretty clear.

json maps may also be encoded to json and optionally decoded to maps (via the return_maps option) To work with proplists, you can use the proplists module. It contains functions such as proplists:delete/2, proplists:get_value/2, proplists:get_all_values/2, proplists:lookup/2 and proplists:lookup_all/2. You'll notice there is no function to add or update an element of the list. This shows how loosely defined proplists are as a data structure.

Whereas proplists would require the use of proplists:get_value(Key, List, Default), maps can use their merge/2 function. According to the specification, merge/2 will fuse two maps together, and if two keys are the same, the second map's value will prevail. This allows to call maps:merge(Default, YourMap) and get the desired values.
