B747 is in a class by itself and is the best plane flying today.
Agreed

A340 is better than the B777 (4 engines, 2 across in Biz, etc.)
Not even close.... B777s two engines provide more power then all four of the engines on 342/343, and only slightly less then the four on the 345/346. And the two engines are two less engines for something to go wrong with. and the 2 across is a matter of airline configuration, not the manufacture of the plane.
A330 is better than B767 (Just more comfy and better all around)
Agreed

A300 is better than B757 (not sure if they are same class because A330 is twin isle)
I personally would much rather the B757 then athe A300

A320/319 is better than B737 (more room!!)
Toss up .. but I do kinda like the A318/9/20/21 family myself. Prefer them over a 73, but not over a 75

Basically I think that Airbus has really kicked Boeing's butt recently and the order sheet is testament to this fact.
156 to 38 on the year .. can't argue with that

The only thing I don't like about Airbus aircraft is the whine the engines make when they begin the takeoff roll.
Thats more of a function of the engine manufacturer .. can't blame that on Airbus.
