The festivals i have been:
dynamo: been there since 1997. That year was best of the years i have been there. It was good, kinda like wacken, but a different, more violent atmosphere (no violence against eachother, but a lot of stuff was destroyed, and i really mean A LOT)
Graspop: smaller than wacken, always good bands, good atmasphere, less comfort in campsite. good, but not nearly as good as wacken.
Waldrock: been there only last year. very small, very short, (there was a camping though) not a very good atmoshere imo. I didn't really like this festival.
Ozzfest 2002: pretty average festival, the good weather and the group i went with made it fun. I think it isn't really a good fest, lotta small kids and stuff.
Bospop 2002: was together with dynamo, while very small, the camping was one of the nicest i have ever been. very good and mature admosphere. I really liked this combination.
Pinkpop 2002: not a metal festival, but wanted to visit as many fests as i could. This was a very big mistake.
Wacken: nothing comes even close to wacken. closest is the old dynamo. 97 was close as far as i can remember, the older dynamo's should have been better, and thus may have been as good as wacken.
The things that make wacken stand out:
-car next to my tent (without bullshit about glass and a max beer)
-camping open days before the start
-metal only, no skate bullshit.
-great atmosphere
