I like 7.
I'd rather that tank in my house than some tank done up for Discus. I don't like discus that much anyway. The grass is too boring, even with the rock in the centre.
7. on the other hand has a nive aquascape to it, the wood flows nicley from right to left and when you reach the end the fish grab ur attention. Great aquascape dude. (soz I don't know ur name)
