The metallic bronze and the satin black are the same finish types. So, I'd guess that they would show wear about equally. I've had a metallic bronze provari since June 10, and there's not a single mark on it. However, I do actively avoid doing things like putting it in the same pocket as my keys.
I can't help you with the blue LED as I have the green. I do agree, it is a bit hard to see in direct sunlight. But, it's not like I'm interacting with anything in the menu more than a couple times a day. So, for the way I use it, it's really a non issue. But, I could see it being annoying if you had some reason to spend a lot of time in the menu while outdoors.
