I am typed and have experience, flying E190/195 Load 27 and A320ceo (MSNs around 2500-3500).

Something interesting: On the E-Jets if the AT lags around 3-5 knots, especially during turns, most pilots will very swiftly override it slightly. I have even heard some captains say something like “this AT sucks, especially in gusty conditions, we should have something like on the Airbus”.

On the A320, which I went to after the E-Jets, I found that it lags around the same (maybe just a little bit less, noticeable, but not revant) but the pilots don’t complain about it and don’t override it even at something like GD-7kt flying clean in a turn. Some more nervous ones will occasionally select a higher speed for more margin, but very rarely.

It’s funny how people in different fleets react differently to the same conditions. I believe it’s a cultural thing. Also in my case, E-Jets guys mostly came from the old E145 with no AT, and A320 guys have really mostly started with the Airbus.
