My pet peeve with Jedi is, that it doesn't support autocompletion for type libraries, that are not parsable python code. For example, anything from gi.repository (i.e. entire Gtk) is then without autocomplete. Jetbrains IDEs do support it: you have to manually generate the symbol cache for the first time, but the IDE knows your intent and maintains it for you, and for you as the user, autocomplete just works. Another thing that Jetbrains has better, is weighing the importance of symbols that are offered: Open a random Django project, try to define a model and see, where the autocomplete makes better sense.
