zeeoo,
I really do like some aircraft, because of the way they handle and lots of other attributes, but I find that stuff is not what makes folks buy or operate commercial machines. It is usually the payload, safety and maintenance ease that determine the winners in our industry.
Personally, I love the Gazelle, the S-67, the S-76, the BO-105, the BO-108 (never flew the EC-135, could be just as nice, I think), the Comanche and the Black Hawk (and its clone the S-92).
