My favourite is the A321 and the A320.
I like the A321 because it is easy to fly, its stable, and it’s not to complacated to land. The A320 is a little smaller, and sometimes get dragged because of the wind.
There is already a topic similar to yours, it would be better to use that existing one instead of making a new topic. I know yours is more specific, but it still overlaps with this one.
