It is almost certainly less-likely than encountering another star. The outcome of a close-encounter between our solar system and another star or a black hole would likely be comparable: Earth's orbit would be disrupted, presumably to our detriment. Black holes of a few solar masses probably aren't any more dangerous than another star.
