I have never cared much for Anthrax or Slayer. I've gone to a single Megadeth and a single Metallica concert back in 98. Megadeth's concert was a fantastic time that I fondly remember. It was basically in what was little more than a high school gym. Great selection of classic and modern songs that were sung and played album-perfect. Metallica's concert was mostly shitty and mostly forgettable. As Hetfield could no longer sing like he used to by 98, he ruined all of their old songs they played by singing them in his 'new' style and also mixed in a bunch of cover songs that sucked. Only awesome thing was Jerry Cantrell opened.
