Fair! But Court of Grace seems excellent. Garruk Wildspeaker is worse against planeswalkers than Garruk, Unleashed, but I think the context for choosing between the two is how the color identity commonly plays out in your pool. I think if White is a midrange to control color, it's worth trying Court over Elspeth, while Elspeth is going to shine if your white cards are more oriented towards early board creature presence. I think another card I've seen a lot that could be replaced with Court for testing is Parallax Wave. It's a very cool and fun card, and it's good, but I think Court is a game winning bomb for midrange decks.
