trust me, I can save you a lot of trouble.
I have Weeping, Taiwan, and Xmas growing on my ropes side by side,
and they look exactly the same after 3 Months completely untrimmed.
I'm convinced these three mosses grow unique based on the tank they're in,
not the moss you use. for example, your Xmas looks more like weeping,
as both my Xmas and weeping grow out and up, not sloped down like yours.
again, it's not the moss, just how your tank manages to host it's growth.

I'm currently experimenting with Willow and Spiky moss to see if I can
get a different growth pattern and texture then those other three.
I suspect Spiky will look the same as the other three, but Willow
is structurally very large and different, almost like a small fern,
so that one will probably make for a more unique wall subject.
If you can wait another Month, I'll post a photo of them on rope
and then you can better decide which one would be wall worthy,
so instead of wasting your time with Taiwan now, I'll send you a
sample of your choosing then, OK?
