Yes, if you can learn how to use the MCDU, then it makes flying the Airbus a lot easier.
Took me longer than intended learning how to fly the default Airbus 320, but have now moved onto the FlyByWire version. The MCDU honours most of the functionality, and more control panel buttons seem to work.
I've also given up using the default ATC, and now using FSHUD. Nice piece of software, but still in its early days. On NZ routes it's fine, but I found on the North American routes it can do some funny things.
