I like that. It's quite easy to use and has really nice visuals supporting the user. I think Adobe Color might be improved upon, but I'd be surprised if Adobe is going to scrap it in favor of someone else's work. However, urging them to take a look at another approach doesn't hurt at all.
Frankly, I'd be happier even if they would simply finally adopt Illustrator's methods of creating and working with color. That's in-house, so you'd think they could do it.
