It's the battle of the Grey's Anatomy big event episodes!

Now that we've seen what Seattle Grace would have been if only Meredith (Ellen Pompeo) was a more bright and cheery person, we want to know: How did this episode compare to last year's special episode, the musical (Season 7, Episode 18, "Song Beneath the Song")?

Both episodes were slightly fantastical, and gave us an unusual lens through which to view the characters. Were you fascinated by seeing everyone living different lives, or did you prefer having the docs burst into song?
