Easier to fly, the Airbus is a piece of p*ss, you point it where you want and it stays there, none of that pesky trimming required. The EK Airbus SOP's are over bearing on a Bus, but have a peek at the 777 NPA's which are a friggin nightmare. The flurry of hands required for a successful outcome is bizarre, plus the variance in procedures if you can't validate the database and have to do raw data. The chances of a balls up are high on the 777. The Bus NPA's are simple, push approach and set missed approach, monitor and your done. Raw data is simple on a Bus.
Yes Bus non normals CAN be complicated, but rarely are in the real world, outside the simulator. The 777 is a well put together plane, good routes at EK, except the long OZ trips, which suits some i guess. The Bus has more turnarounds, but again that suits some folks.
Best fleet at the moment is the 777, the Bus will be up there again when the 380 arrives, lotsa promotions then.

But one thing hasn't changed for sure and that is that 777's are easier to fly, easier to deal with SOP's and in general are better aircraft, but that is just my opinion. In addition, there is far less 'talking' required on the flightdeck to get safely from A to B, in a Boeing than on an Airbus. I won't even get into the relative simplicity of Boeing procedures as compared to Airbus.
