Iris:
Nice handling
Campro engine is nothing to shout about.
Punch CVT gearbox is sloppy, changes gear like old man, rubber band feeling.
Low resale value.
Since geely took over proton, campro engine is seeing its engine end of life, meaning less spare parts in the near future.

Myvi:
Handling not as good as iriz.
The rear passenger will feel the rear suspension stiffn bumpy due to the light weight n simple design of myvi rear suspension.
Engine is from daihatsu with
Toyota technology.. meaning long life engine.
Gear changes is smooth n fast.
Fuel consumption is normal.
Car is zippy.
High resale value.
Lots of spares.
