I like the second one more. You have to be careful when using some sort of bump-texture/caliuquer thing as it's really easy to spot if its covering a large single area. The second one seems to have abit of a variety in the texture while the first has an unvaried overlay over the whole patch.
Interesting, thanks. I'll probably use some variation of the second going forward. I'm still learning how to do this the best way I can!
