Having flown both types in a "Low Cost" environment a few years back, the Airbus wins without a shadow of a doubt. I flew the Classc 73 as well as the NG btw.
To OPERATE, the Airbus flightdeck, is quieter more spacious and more comfortable, it makes for a much less tiring day out...
To FLY then it has to be the Boeing, I am glad I started on it, it gave me some invaluable experience and handling skills...
