Which baby rice product should I choose?

​I was looking into baby food products for my baby. In order to get the most out of the price I pay for the product, I want to buy something that has the highest price-performance ratio. 

I would like to choose from Hipp baby rice and Gerber single rice cereal, which is now with a new look. However, these two similar products are packaged in different shapes of container. 

So, which one should I choose considering only to get the most out of any pennies I take? Any thoughts?
