exactly, which is why i'd go with vader. it's like choosing between napalm death and nasum. i love nasum, but they were influenced by napalm death, so i have to choose napalm death.
I would say Decapitated, but only because they learned everything they know from bands like Vader. If I had to only listen to one or the other, it'd be Decapitated, but I'm glad they're both around. Two awesome bands.
