I've been trying out Feisty for the last day, and while it's an improvement over Edgy I don't feel like it's better than Bianca. Bianca is still a more complete out of the box system with great homegrown apps, and the only thing Feisty has over it is having the latest versions of everything. In my case, these upgrades actually seem a bit less compatible with my system, and my Feisty isn't running as smoothly as my Bianca. My laptop is over 4.5 yrs old, so maybe that's part of the issue. People seem to be raving about Feisty over at the Ubuntu forums, but maybe that's because they've never tried Mint
People come from Windows and discover Ubuntu first and think "Exotic. Rebellious. Non-Windows!" before they learn that there are other very viable distros out there, a few of which are better. I did the same thing with my MacBook, but then bought a ThinkPad and installed Zenwalk on it. I distro-hopped for a while, finally landing at Mint which, as long as it remains healthy and current, will be stuck on my laptop. I reinstalled OSX on the other one...but enough with my tangent.
I was relatively unwowed by Ubuntu coming from the Mac world. I imagine that it would seem that amazing coming from Windows though...I had been using Edgy, and was so unimpressed by the Beta of Feisty that I decided I wouldn't wait for the release (I tried MEPIS and Etch instead) and finally took the bait and went for Mint. Mint matches Zenwalk's speed, Sabayon's looks, and Ubuntu's expandability, which is the only part that's at all "borrowed." It has the best theme I've seen for GNOME, and overall blows away other distros I've tried.
As a Mac user, Windows users always looked like sheep to me (comparing pay-for software). Now, as a Mint user, the same goes for Ubuntu users, whose choice I think is controlled by an ignorance about distributions. But if they're at all curious, they'll discover what's out there soon enough. The tough thing for Mint is its reputation as a "modified Ubuntu." As I tried the various distributions, I avoided Mint and MEPIS because of this reputation, assuming they would be lightly modified, rebranded Ubuntus.
