I went with a dark tinted and you definitely can't see through it. I had a mirrored/colored blue one for my past Shoei and I let it ROLL on the ground on and the visor got scratched. Didn't affect the view from inside at all but didn't look to hot from the outside.
I will probably never get another mirrored one again. The expense wasn't worth it. And you can wear a mirrored in the same light conditions as a dark smoke. I suspect the light smoke allows you to use it at dusk at least, and the dark smoke gets dicey at that point.
