Depends on what you want it for, doesn't it?
Science can tell me what is messed-up about me. It can tell me how it's messed-up, how it got messed-up, and how it would work if it weren't messed-up.
It cannot tell me why it's messed-up. All science can say is that it's hereditary, or bad luck, or an environmental toxin or collection thereof. Random. Whatever. It cannot supply me with a Big Why.
For that, I need philosophy, or religion.
Philosophy and religion can give me good whys that make me feel better (indeed, even not messed-up at all) or bad whys that make me feel even worse. But at least they can give me answers.
Science is probably more correct if you need data.
If you're looking for gestalt, or raison d'etre, or whatever word you prefer for what I call Big Why or "a reason to keep getting out of bed in the morning," then religion/philosophy is probably more likely to yield useful results.
