Sccutler brought up a good point. Most passengers will not know what kind of airplane they're flying on anyway. They're all gonna think it's a 747 anyway!
I personally like the 737-100 and 200s better than the A320 and even the newer 737s.
I like those loud engines on the older 737-200s.
I think the A320 just looks so boring and the whinning sound at takeoff doesn't impress me at all. I like roar of an old 737 better.
Airbus is equally as good as Boeing, Tupelov, Fokker and all other manufactures so expect no wars from me.
Good luck on your project
