I think that registered users should be able to use Preferences to choose the style they prefer. If I had to choose one of the three, and had the ability to choose, I think I would choose 2.

Individual wikis should at least be able to adjust the background color and/or transparency, and maybe even be able to say "Search this wiki" instead of "this wikia". The white background can be jarring against darker themes. Also, the light gray used for "this wikia" in the search tends to blend into the white background.
