Slash was still angry/badmouthing Axel earlier this year AFAIR.
G'n'R has got several really good songs (for me, at least), and much of it is Slash's playing. He's really a great guitar player, instantly recognizable, all praises, but as SMX said, a lot of it came down to their youth and lifestyle. Their album sound isn't heavy enough for me, Izzy is a rock'n'roll guy and his style is great for what they did, because there was abudant energy. Now they're grown up men, they can't recreate that any more, and if they don't change their sound, it's going to be weak. Their original sound is not heavy, at least compared to 'normal' heavy metal...
I'd really like them to play songs such as Nightrain and You Could Be Mine with a real heavy, modern sound. Not keeping my hopes high, though. I'm far more enthusiastic for Rainbow 'reunion' shows coming up.
