Which calendar power-up is best? Are they all essentially the same?

[Brianne_Kane]

For various reasons connecting Trello to my Google Calendar just wont work (more confusing than helpful) so I'm looking into various power-ups through Trello (since I love my board and rely on it entirely.) I've looked at Big Picture and Planaway, both seem good but basically the same thing -- my question is what are the differences between the various calendar power-ups, and which one do you think is best?

Hi Brianne, here's an article I wrote a few weeks ago about the different Calendar Power-Ups you can use in Trello.
