Yes the IVECO is as reliable as the Cummins, but suffers non recognition in the US market, being basically the same engine. Most in the US will see the " Made by Fiat" label and steer clear of it.

The Iveco 6.7L is not "basically the same" engine as the Cummins 6.7L. The Cummins has a larger bore and shorter stroke (107mm x 124 mm) than the Iveco 6.7L (104mm x 132mm). This alone will make the characteristics of each engine different with the max engine speed being lower in the Iveco(less horsepower). They also have different pistons, rods, and many other internal parts. Their compression ratios are different too with the Cummins having a 17.3:1 and the Iveco having a 17.5:1 compression ratio.

Both the Cummins and the IVECO 5.9 engines were the product of the short lived partnership between Fiat and Cummins.Fiat actually produced the blocks for Cummins, before the total separation of both companies.

With very little time left IVECO turned to Cummins.

In the meantime Cummins had their own problems, having made a huge mid life investment in the turning the successful B and C mid range engines into a four valve electronic engine range. The four valve the 'Emerald' program resulted in the in the front gear drive Bosch VP 44 quasi electronic ISB engine. A shed load more cost without very much gain.

IVECO by chance were gifted a little gem. Ford wanted out of their loss making tractor business and sold Ford New Holland to Fiat. Ford had some super guys designing high pressure pumps who had come up with a very simple a clever fuel lubricated common rail fuel injection pump. Fiat dumped this new pump onto their sister company Marrelli.

Marelli KNEW that Bosch were in deep trouble with their oil lubricated CP2 common rail fuel pump, too late, too expensive and unreliable. When offered the original Ford concept pump they bit the hand off the italians. Part of the agreement was that Fiat had control of who the new pump could be sold to.

The EEA brought together engineers from Cummins UK and US, IVECO and Ford New Holland. Using the ISB engine as design base around the new common rail pump the team working from rented offices in High Wycombe worked at speed. 102/120 bore stroke cam location, 4 valve cylinder head was retained, everything else was torn up.

New engine had the timing gears moved from from the front to the back, cooling capability upgraded, lube oil system changed to J jet piston cooling nozzles.

Fiat carried out a lighting strike on Case tractor who were building the B Series in Germany and scooped up the bang up to date production line and machine tools.

The final result of the EEA work was the ISBe automotive engine built by Cummins in Darlington and the Italian IVECO NEF engine. Very similar engines, however IVECO use Bosch Hardware/software, Cummins used Bosch ECU with Cummins software and slightly different common rail set up.
