I've found them to be pretty similar:

For my 2c worth the 2.2 is a better engine, more drivable, better power range. However the only place I miss the 2.4 is on the highway, put your foot down in 6th anywhere above 80km/h and it would go, the 2.2 you are back to 5th, (I know its lazy driving and I deserve a kicking for it, but hey).
However I do find the 2.2 is more happy at 100/110km/h than the 2.4. The 2.2 loves to rev, and I've had a few passengers think it's a petrol.
Cheers,
Tim
