I got an expensive cooker and can tell the difference. Cheap 3 cup cooker to 10 cup bottom burner to Zojiriushi induction. The same amount of rice cooked would not fit in my rice saver container for stir frying without being smushed down because it was more fluffy.

It takes 3 times longer to cook however yet has not burned my rice when sitting on warm yet. I get happy when I smell the fresh cooked rice several times per week so I'm definitely in the worth it category.
