Well then you would be a better judge than I. I was in Junior High/High School during the hieght and fall of popularity of Heavy Metal. So I only got to a few concerts of any Metal groups. Grunge had taken over by the time I was graduating from High School. So my music taste had changed some. Was the concert worse than the GnR concert were the fans rioted due to the band being late?
Probably not, the floors weren't ripped up, but chairs were flying, people were getting punched for no reason, fires got started. This was mostly people who were in seats all wanted to be in the pit and dam the security.
