Are you talking Goblin or Goblin Mini?
Zephyrus is superior to original Goblin hands down. You can access build with half full
tank, A LOT more airflow (both outside, inside, and chimney diameter), top fill, bigger build deck.
Can't speak to Goblin Mini because I think that RTAs without deck access and with bottom screw fill only are OUTDATED and I'll never purchase another again.
