That's the way I was before owning one and listening to all the BS people said without actually ever owned one.
I've had 12.7, 14.0 DD, 3406E, 6NZ C15 CATsand a couple of N14 Plus and they're excellent engines, no doubt.
But after you do a MM2 on this engine no Detroit or CAT can touch it with the power/efficiency it has.
