Pretty much all the same, A320 series, A330, and A340, just larger bodies, and engines, as far as they go....MUCH better than Wilco's Airbus A320 and A380.  The PSS ones are not super realitic since they are not completely FBW, although neither is the Airbus itself, go with the PMDG 737, or WILCO ERJ or CRJ, better yet why not try the Level D 767, looks fantastic 

What was the thing that is FBW, that is not completely FBW, I thought the Airbus FBW was not complete or something like that...I no that sounds stupid, but I swear I saw something about that,ahh maybe I'm just seeing things

The airbus FBW (fly-by-wire) system is all handled by computers (ELACs and SECs, which stands for ELevator And Aileron Computer  and Spoiler and Elevator Computer)            
                                                     
In the airbus A320, the control surfaces are controlled by the already mentioned computers, 2 ELACs and 3 SECs

Now you have 5 different computers and ANYONE of them can work the entire system. Two different software languages are used in the programming and the hardware is made by two different manufactorers, so the chance of losing all 5 is virtually impossible.
So it's complete allright 

While the 777 boasts FBW aswell, the FBW computers aren't able to override a pilot command, like in the 'busses. And unlike Airbus, a 777 pilot needs to apply backpressure to maintain attitude in steep turns, ie roll control is similar to conventional airplanes
