You honestly want to compare Bon Jovi on their best nite to any current GnR show?
a) GnR was always a much harder rocking band just by nature of their music
b) yeah - they were SO powerful that their lead singer had a complete mental breakdown and had to cancel the rest of the long-awaited comeback tour (either than or all the cornrows and botox injections seeped into his brain and his frontal lobe melted.)

Those who live in the past are condemned to stay there...
