What's the difference

In the supermarket, I asked a female worker who was passing by me when I was standing in front of the rice product. I asked, what's the difference between this two? She tought for a while, seeming to search the fittest English words to explain to me.

"This one is better!", she pointed one of them and said no reason. In fact, I wanted to know the difference because they are the same brand with different flavors.

I listened to her.
