First and third are great. BUT...it's not about what I think

If you're shooting for the Irish Chain, then others have had very valid points.
As a Nine-Patch, either of 1 & 3 are very nice (again, IMO)

If you are really liking one in particular of these three, perhaps the IC is not the pattern you should shoot for with these fabrics. It's very easy with these blocks you're using to take a different road at this stage of the game. If you don't like ANY of them, you're not so far in that you have to be pained with finishing something you don't like.
Perhaps research more images of nine patches (any variation...I'm betting that a DP9 would look fantastic with your current fabric choices), and also check other Irish Chains to see what you really are drawn to, and go from there.

I like how the colors pop in the one with the black

I have a problem with the green squares in the 9 patches. They are too similar in color and value to the background - in both 1 and 2.

I like the second one best. Guess I am just different? That's okay. I am glad we don't all like the same things. How boring would that be?

Love the fabrics in the first one, but I also like the block with black, probably not much help, but you asked. Actually, any of them would work, as I love the fabric for the plain squares, gives the block more depth.

1 and 3 if you used a black border. Love the colors.

I like # 1. Very pretty.

Nr. 2 or if you want the pop--use ALL black for the background and the colored batiks for the 9 patches corners/center. It would be gorgeous!
