It's not the noise level, but the sound quality. A co-worker has a 2009 Escape, and our neighbor had a '10 Escape for about a year. The engine noise is not all that "refined". I can tell you from personal experience that other V-6 engines are far more "refined" sounding, to me. This is very subjective, though, which is why you'll get a million answers to the question, "what does a 'good ride' mean to you?"
I wonder if it's intake manifold noise/resonance. Do they have a sound-deadening cover on top of the engine? If I remove the sound-deadening cover from our Acura's engine, the engine sounds noisier and grainier. Still not as loud in a Duratec in an Escape, but at that point, vehicle insulation is probably the difference. I think most Duratecs use plastic upper intakes...if there's no sound-deadening material on top of the upper intake, I'll bet that's where the noise is coming from.
The Duratec isn't the only modern V-6 that sounds noisy to me. Toyota's 3.5L GR-series engines (at least in the Sienna and Venza I've driven) sound like they're lubricated with marbles. I also don't care for the sound quality of Chrysler's new Pentastar engine. It sounds pretty grainy. There's no comparing these engines to a Honda V-6 or an older Toyota MZ-series V-6 like the former 3.3L in the Sienna. This co-worker of mine with the '08 Escape, he just traded an '04 Sienna for a '12 CR-V. That Sienna's engine was a model of V-6 refinement. Another sweet-sounding V-6, to me, is GM's HF V-6 engines, like the 3.6L in the CTS. Super-smooth, super-refined.
Left out Nissan's VQ
