That depends on what you're measuring. "Worse" in terms of uncertainty? Or difficulty? Or complexity? Or harm? Or what? And "worse" in what sense? Worse in the sense that things would be better if it weren't true, but it is true, so we have to face reality and cope with it? Or what? The question is too ambiguous to answer.
The question is also moot. It's always worse to believe in what's false. Thus even the worst thing about the truth is better than any mistake or lie. So you should be asking which worldview is true, not taking stock of whether you "like" one more than another. It's better if you learn instead to like what's true, rather than what you think will be comforting.
