Rang Bloon functions almost identically to Bomb Bloon but grants a Boomerang Monkey. Boomerang Monkey costs more than Bomb Shooter, lacks utility and initial burst of damage, and has poor single-target damage. Boomerang’s poor stats generally make Bomb Bloon a better option.
Although the stats of the Bloon itself aren’t horrible, building defenses from only Boomerang Monkeys is not recommended. Early on, 1-delay aggro and early Large Bloons will overrun the player before creating a full Boomerang setup, along with Boomerang’s poor single target damage making it weak to Bloons such as Blooming Bloon.
