To be honest, I know nothing about that album and couldn't even tell you what songs are on it. The only GnR I have ever listened to is Appetite for Destruction, and it has been a while for that one too.
Appetite was pretty juvenile. 'Illusion II' is a whole different beast with much more depth. Try the songs 'Locomotive' and 'Breakdown' and be sure to read the lyrics. You should get it pretty well considering your high regards for the Pumpkins. Not the same style, but lyrically similar...albeit a bit more direct in Roses.
