DragonForce is epic speedmetal and Metallica is early metal.
They really can't be compared because they don't play the same type of music. This is like comparing Eminem and Insane Clown Posse because both singers like to rap. It just doesn't work.
I'd have to say metallica because dragon force is a 1 hit wonder and their one hit suck monkey fuck. the members of their band all have absolutely no talent Dave Mustaine can do a solo better than an 11 year old
wat the ****!!!! Dragonforce's drummer sucks the most out of ANYONE, and I hate they're guitarist, he's less than average.....I HATE DRAGONFORCE!!! On the otherhand, Metallica has my 2nd favorite drummer, my 2nd favorite guitarist (while being the best), and used to have Cliff Burton (RIP). Metallica beasts Dragonforce in every aspect.
[b]DRAGON FORCE ARE CRAP. Everybody only listens to "through the fire and the flames" which is a bad song anyway but the others are even worse, and their one of the worst bands live in the world. Mettalica arnt so good these days but their old stuff is awesome.
