I came from the 737 to the 320 and found it incredibly intuitive after the initial introduction. I went from the 320 to the 220 and we all know the cannabus is no airbus. With all the FB’s and a plenty of choices to do one thing multiple different ways it took more time to get used to then the 320. Don’t get me wrong the 220 is great and flies significantly nicer than the 320 manually. The trickiest thing about the 320 is probably the box, ECAM song and dance, and flysmart.
