which doubler should I get...bamboo or hemp?

new2atl

I have an amazon credit I'd like to use for an overnight doubler. Which is better:

Babykicks super absorbent hemp/certified organic cotton fleece.

or

Bamboo baby cloth diaper inserts. Insert is made out of 1 layer of bamboo and 3 layers of microfiber

 If there is something even better that you would recommend (that is sold on Amazon) please let me know.
