the Fairchild-Dornier 928 is really a decent plane, if you speak about him. Not as good as the Ejet, but in GW3, it's much cheaper to buy, so it can be a good idea anyways. And the Fokker120NG also has good qualities, in its niche.
(the fact that the F120NG will never fly is not official, but well...)
At the end, this game is about statistic. Look at all the stats, and then make the decision according to your strategy. For a quick expansion a cheaper-to-lease plane can be good, for long-term survival, costlier but fuel-efficient planes could do the job, etc(and both strategies can be dangerous)... Whether the steel you fly has a real life equivalent should not be part of your decision process.
