Safer car, iriz
Reliable car, myvi
Better handling, iriz (if it matters to your sister)
Spacious, myvi
Power and responsiveness, I would say myvi. I've driven iriz 1.3MT before. Acceleration is like brownish toxic discharge from the bottom hole of a human body.
Fuel efficiency, myvi is not bad. Iriz MT should be ok too. So far what I heard is that Iriz AT isn't really a fuel saver
