Hemp vs Bamboo Who will win?

I have been wondering this question for awhile, but then a mama on a FB page asked too. So I decided I would test this with my hemp/bamboo inserts.
I have mostly hemp inserts, but a few Blueberrys bamboo ones, so this test is a bit biased, but I think it's still valid.
Test Subject:
Blueberry bamoo large insert 70% bamboo 30% Organic cotton
Thirsties Hemp prefold 55% hemp 45% cotton
Hemp Babies insert 55% hemp 45% cotton
Green Mountain Diaper insert 55% hemp 45% Cotton

All of these I love for so many different reasons, and I super happy to share my love of them with you.

only one is missing is the GMD which I added later. . . Plus it doesn't have a tag

Hemp Babies-6 oz in the jar to start out with

Now only 3 oz left in the jar= Hempbabies holds 3 oz dripping wet

Thirsties next to the 4 cups or  32 oz

After: 1 1/2 cups or 12 oz!

Blueberry Bamboo doubler

1 1/4 cup or 9-10 oz

9 oz of water and trying out the GMD hemp doubler

This was just funny looking at!!! lol

5 1/2 oz left so that means this super thin doubler holds 3 1/2 oz

Here are the stats.

 Now looking at my poster board, with the hemp doublers there was a pretty equal ratio of the cotton and hemp (55%/45%) but it held just as much as the bamboo ones but had a higher content (70%/30%). So this in my mind is telling me that hemp does in fact hold more than bamboo.
