People constantly want to talk about what they think is "the best" plane. Further, they define "best" in terms of capabilities like speed, range, capacity, seat width, ease of handling, etc. What they must understand is that by themselves, none of these capabilities matter to airlines. To an airline, the "best plane" is the one whose capabilities and costs (both acquisition and operating) allow them to make the most money. Such a plane is rarely the one with the most capabilities.
