The question that we should be asking is: Where is customer preference (as subjective and varied as that may be) on an airline's list of priories when choosing an aeroplane? I'm not sure it makes the top 5. I would guess the top ones are:

• CASM
• Range and CASM variation as it refers to range
• Maintenance requirements & costs - espeically engines (what mainly killed the A350-1000 for EY)
• Cargo capacity
• Crew training requirements

No airline is choosing a model because they think their customers will prefer A over B. There is little to no significant differences between comparative models to influence the choice, so that part simply becomes a job for marketing to say that the choice was to offer a better product to the passenger.
