Aero bars are more wobbly by design as your centre of balance is more concentrated than with regular, wider road bars. This is one of the reasons that they are only allowed in non-drafting or time-trial races. They would be too dangerous to have if everyone was in a peleton.

Properly setup aero bars are not wobbly once you get experienced using them. It takes some time to get used to the position and feel comforatble and confident.
The reason they are banned in mass races is your hands are too far away from the brakes to quickly stop.
