Boeing is by far the best entry aircraft at this time. However in 2 years you will wish you chose the airbus.
You can look at all the reasons of pros and cons airbus or boeing but my reply is purely lifestyle and not type.
A343 A332 will be all gone within 2 years which means the Boeing will be doing its current jollies as well as picking up all the crap the bus boys do today. The A345 will remain(for the time being) but most of the bus drivers will go to the A380 which is BY FAR the senior flying club/fleet to be on for excellent day flying and decent trips.
Regarding the A350, I believe that EK might be considering dumping the order of the 900 (they wanted the 1000 and the 900 is now delayed anyway). Boeing have the 787 flying and a 777 made with 787 technology will be far superior than the A350, so you see that EK is going to become...... A380 prime layovers or boeing nice layovers with all the crap to dilute the fun. Future expansion would be a mix of A350/1000 or 777/787 hybrids and the 90+ A380s.
I hope this helped (stir up the crap???)
