In the end, I think you'll find the usual suspects provide the biggest bang for your buck (USA and maybe the Netherlands).

Any trade up in freedom quickly seems to trade off for corruption all the way up to the Wild East of Moldova where everything is legal as long as you pay the right people (but don't dare criticize those from whom you're buying your "freedom"). Any increase in stability/non-corruption trades off for civil liberties (Britain: unchanged since 1660 and SMILE FOR THE CAMERA). So yeah, your options are limited.
