The 2.7 is also a fine engine, though search around and you'll find it too, can be prone to failure. So can Nissans, Toyotas, VW, etc.
If I was in the market today, I would still be leaning towards the 3.0, however if a 2.7 D4 came up with the perfect configuration for me I wouldn't have any issue buying it. The 2.7 has the benefit of 18" OEM wheels, the 3.0 has more grunt, newer gearbox, etc.
But service history is far more important than anything else.
