Ninja vs boomerang top path

Hello, I have a question as an unknowing companion:

Is there a point in using a top path ninja over a top path boomerang?

I mean, a 4-0-2 boomerang is better against raw numbers of bloons as well as against large numbers of heavier bloons like ceramics than even a 5-0-1 ninja.

A 4-0-2 boomerang costs ~1.400 less than a 4-0-2 ninja(at easy)

A boomerang can pop lead bloons

(Yeah, the ninja can po camo)

The only thing the ninja top path is slightly better in is that it deals a bit more damage against MOAB.

But I mean, therefore, it costs more and usually you buy something different to deal MOAB-damage.

Thanks for your time and your comments to help me understand the ninja better since I'm pretty sure I'm just not considering everything :3
