I like them in the same order you listed, 1 is my favorite, 2 is 2nd, 3 is 3rd. However, I like 1 and 2 quite a bit better than three.
It's hard to say my opinion because I assume you may angle things a bit differently once you have substrate.
I love #1 as it really shows off the character of the largest stone. However, with #2, you get the character of the large stone left of the main stone (don't know the Japanese terminology). Have you considered turning the two left rocks around on the left side. It may look more "tranquil", maybe not lol.
I think the first 2 will look great, just kind of nit picking.
