The Airbus offerings are really superior for comfort to Boeing's old 73x cabin design. Boeing just keeps stretching the same 50 year old tube design and putting on new engines and claiming its better but the same from a technical aspect for training/maintenance... which we know it isn't.
There was a long time where I preferred Boeing planes, but that has switched dramatically over the past 15 years. The last model that Boeing did really well for narrow body was the 757.
