Choice number 1. I don't like splitting up the mid and tweet, they cover a range that either speaker can be reproducing the same instrument (yes I know this could apply to the midbass as well, but you can't usually fit all three in the same space, so I consider this the lesser of two evils). Mids and tweets on the dash at the far corners and midbass in the kicks is how mine is set up now, If I can find the space (and time to build it) I'll move the midbass up there too.
I am also not opposed to a nice small set of tweeters with minimal power crossed over in the 16k+ range at eye level in the a pillars. But that would be icing on the cake in an otherwise complete front stage, I would rather put those resources into a better set of main speakers first.
