I mean, I'm not exactly unbiased. But I love the Episcopal Church because it is open and accepting, doesn't have many of the non-Biblical and questionable aspects of Catholicism, and also encourages critical and historical reading of the Bible. Just take it from Robin Williams.
The book Always Open: Being Anglican Today (since the Episcopal Church is part of the world-wide Anglican church) is a great (and short!) overview of our beliefs and history, if you're interested.
