As far as I know the only difference in the Aerobat is it's beefed up to take aerobatic forces (actually I'm not sure the structure is any different to a standatrd 150), and has jettisonable doors and removable seat cushions for fast parachute-equipped exit, and 4-point harneses. I flew both years ago and detected no handling differences between them. Or indeed the 152 that replaced the 150 - except the limitation of only 30 degrees flap in the latter.
