First off: YAY!! Another Day convert!
I love the Day -- the moment I laid eyes on it, I knew I had to have one. I have a Tomato RH Day and it's the most comfortable/versatile/functional purse there is! As for RH v GH, I don't know how the GH slouches with time, but I think the RH Day should slouch quite a bit with use. Love the slouch!
Good luck with your Day quest!
