Cummings never had a good reputation for diesels, they were considered at the bottom of the list. CAT, Perkins, Mercedes, Detroit, others were preferred.
I can only speak from my experiences. I own a bulldozer, 1987 Case 850D with 6600 hours, the engine is a naturally aspirated Cummins, never been apart and no failures. The other is a 2001 Dodge 3500 reg cab 4x4, Cummins with a manual. Again, 300k miles and engine still going strong, never been apart. That's all I can speak to. Never owned a Cat, Perkins or Mercedes. I have worked on Detroits, noisy, oily beasts but do tend to have some longevitiy.
