I tend to disagree with some of the above said.
In the early 2000 my company hired a few Swissair F/O. Those pilots had exclusively flown the A320 after leaving flight school. As our A320-fleet did not need anyone at that time, they had to fly a conventional aircraft. It took them approximately one hour of simulator training to adapt the lack of autotrim, even though they had never flown an conventional airliner before.
In my opinion - and I have flown conventional aircraft as well as Airbus FBW for more than 10 years (each) - normal law (= bank- and g-stable) does not make flying that easy, that you don't have to train manual flying. To test handflying skills, it was pretty common to challenge new pilots with an raw data manually flown NDB-approach in the sim. In my experience the results were the same in the EFIS 737 Classic and A320, which shows, that trimming the aircraft and correcting bank is not a gamechanger!
I agree, that - as vilas stated - the scan is vital. However: Following an FD with A/THR on will not help to improve scanning. The only way to accomplish that is raw data flying, which should be practiced more than in the mandatory simulator sessions. For decades A/THR on with A/P off was forbidden in my company. I am not aware of an low speed landing incident in our A320 fleet (35 years!).
