I don't know if you can claim one is more straightforward. Sure a Cessna flies slower and has relatively simple aerodynamics. However, you could also be operating it out of a 400m sloping grass strip with a mountain off one end.

An A320 might be flying 3 times faster but is generally flying between relatively flat, straight runaways several miles long with approaches typically flown on a stable instrument approach from several nautical miles away. It's control laws mean flying straight or maintaining a particular bank is as simple as letting go of the control stick. If anything the stick and rudder skills in normal circumstances are much less involved. Systems management, obviously the autopilot, but also environmental, hydraulic, navigation an the operational concerns are obviously vastly more complex.
