The 737 is the most commercially successful jet airliner ever produced. Given that it is still in production and that the new version of it already has orders and it’s not even a prototype I’d say that even if an engineer didn’t like it that doesn’t matter because the engineer’s employer does.
Nothing I can disagree with there. I certainly do not consider myself a 737 detractor; as you say, it has been an unqualified commercial success.
I now realize that it was you who made the absurd claim that the SJ 100 is a “rip off” of the 737. You ought to apologize for that.
