Not sure who the "D" is aimed at. Must be Corporate, 'cause offshore could care less about ice or how quiet the tail rotor is. In these financial tailspin days I don't know whether a cheaper 76 is any easier to justify than a 139. I disagree on the ride though, the 76 is 'way smoother than a 139. Most offshore guys don't bother with the second bifiler, but the Corp guys do. If the de-ice is half decent it might make a difference - the 139 de-ice is best described by that historically appropriate Italian word "fiasco".
Cockpit is nice. I think they should have gone with something other than Thales and their rollerball controllers, maybe the same setup in the Bell 429.
Engines, hmm. The Pratt's are good, but it is going to be hard to beat the track record of that sweet Arriel 2S2 with the best FADEC on the market. Power, economy, reliability.
Nobody compares it to the 155? The 139 and 175 are both in the 7 tonne league, apples to apples what else is out there under that magic 5.7 (12500)?
