"I'm Hilton Gold and...I wonder what it must be like to be Diamond?"

Though this is a comment made by stimpy in an accompanying thread, I too am HHonors Gold and have wondered about this. As an SPG Platinum, Hyatt Diamond and Marriott Gold, and so forth, I've been inclined to stay elsewhere and I'm particularly curious whether it is substantially worthwhile to attain Hilton Diamond?

What are the facts here, and the experiences of FT'ers? Thanks in advance!
