Would not recommend ANY rating, unless you are offered a job at the same time.
All time Airbus fan, confort, technology, ergonomic and logical cockpit. However quite tricky in degraded mode, therefore flying in normal ops makes you think you can master all, but give a couple of failures, and you better know your aircraft, it can throw you a picture you may not like if you don't understand it.
Would never want to have a yoke in front of me again. Long term options are good, common cockpit with 330/340, you could get rated on another type in a week.
Dunno 737, not interested. For me it's a dinosaur. As I read once in a popular flight magazine: 737NG is like having a 1962 Ford Cortina, and fitting a Mondeo's dash board: it's still a Ford Cortina...
Loved the 727, although on got a one time ferry and a few jumpseats on it.
But again, without a job, it would be a waste, or at least a huge gamble.
