Definitely Mars. Venus has to thick and dangerous an atmosphere and Mercury is way to close to the Sun. Mars is basically just a giant cold, red dessert. As long as you suite up, and have a sheltered place to live in (including food and all) you could live there just fine.
Mars would be the only other choice (if something where to happen to earth). It has water in the form of ice at the poles, and, though it has no atmosphere, we can "crack" water to get oxygen and make our own atmosphere inside our protective dome. We'd have a few problems with radiation and the winds of Mars, but as regards a new place to live, it's the most doable.
