Demoniac were a heavy metal band from New Zealand formed in Wellington in 1993 by singer and bass player Lindsay Dawson, guitarist Sam Totman and Drummer Steve Francis. They later moved to London, UK. Three of the members went on to form DragonForce. Their rather unusual musical style has often been labeled as "blackened power metal".

Can we draw the following conclusion?
Demoniac was better than DragonForce.
It's impossible to say
