I suppose the one fair generalization is that some prefer aircraft with three or four engines (e.g. 747s, 340s, MD-11s/DC-10s) overwater to twin-engine birds. For reasons of safety and peace of mind.
P.S. I'd prefer the Concorde any day of the week were it still available and were somebody else to pick up the tab.
Twin engine birds are every bit as safe as quads and tri-jets. No twin engined aircraft has ever crashed due to the failure of both engines EXCEPT in the few instances of fuel starvation, but that's irrelevant because the same outcome would happen to a tri or quad jet.
I know I'm in the minority here, but seeing as I always fly cattle-class, I much prefer the 767 to anything else. Give me a window seat and I'll only have one person to climb over, and the Y cabins on 767s don't feel nearly as packed as larger widebodies do. Even if you're stuck in the middle seat of a 767, assuming 2-3-2, you'll only have one person to climb over and you can vary which person you climb over each time so as not to anger anyone.
