Hah! I don't know much about tattoos, but I'm pretty sure a subtle effect like brushed metal would be quickly and easily lost. a gradient chrome look would last longer, but probably need touch-ups regularly if it was done lightly.
I definately think you should go with a bevelled edge and chrome gradient look, so that it's more similar to the original logo and people will sort of recognize it.
Personally, I wouldn't tattoo myself with anything that wasn't DEEPLY significant to me, but I have no idea what the story behind this is, and people can do whatever they want to do to themselves.
