Anyone who loves the sound of delay. Nothing beats the feeling of pressing that delay pedal and getting closer to that lovely, late-80s, cheesy sound that is now really unfashionable. I always use loads of delay, particularly with guitar solo's. Anything that make me sound closer to Def Leppard has to be good.
Also, delay was used a lot in the early 21st century Nu-Metal scene with bands like Limp Bizkit or Linkin Park.
