I find Slash has his own playing style and sound, and he's pretty good at it.
The problem with Slash is that that's all he does, I don't see much innovation or versatility in his work (over 20 years of career).
What I like about Chinese Democracy is the shifts in style and the departure from the old GNR sound -although it still keeps some of its essence.
It took Axl a long time, but he's a visionary and came up with a great album that captures different influences. He's not afraid to venture into new territories and give it a try. I think that's one of the main conflicts with the old line-up... while some (if not all of them except Axl) wanted to keep doing the same, he wanted to explore a bit... and I'm glad he didn't give up. I love all GNR albums, but Chinese Democracy is BY FAR the most interesting to listen to, at least in terms of what I value in music.
