You're making assumptions that your definition of "perfect" is the same as everyone else's. There are cultural differences with respect to the preference of the actual texture and stickiness of the rice.
For example, my Chinese parents basically don't like the stickiness or texture of rice made by any other culture. It might be close minded, but it does illustrate that different cultures have different standards for what makes rice "perfect".
