Best for what? Teaching a code of ethics? Giving life meaning? Actually empowering people to reduce suffering? Giving people a sense of being part of something bigger than themselves? Assessing how each does on these various aspects of what religion is for might be more fun/inspiring/interesting than whatever you're trying to do here.

@WilliamGunn The one that's best at conquering and subjugating infidels. Christianity and Islam are the only serious contenders.

@skibidist Hinduism and Buddhism also have vast numbers of followers

Zoroastrianism

Voted Sikhism because my Jewish friend said they should be in charge of everything. I'm an atheist btw.

...and they didn't state in comments!

@EnopoletusHarding I think it's mostly atheists who follow secular ethical philosophies (e.g. utilitarianism, virtue ethics, deontology etc.)

@TheAllMemeingEye They should still state what the best religion is.

@EnopoletusHarding Very well, personally my choice out of any religion/philosophy is utilitarianism.

If restricted to only the named choices in the poll, it becomes much more difficult. I know a medium amount about what Christianity, Islam, and Judaism say about the universe and morality, but I also very strongly disagree with the teachings of all but the most strongly revisionist liberal denominations. Meanwhile, I only have an extremely basic understanding of what Buddhism, Taoism, and Sikhism say, and I know literally nothing about the teachings of Jainism and Shinto, so it's hard to decide whether they're likely to be better or worse than the Abrahamic religions.

Btw is there a reason why relatively small religions such as Sikhism and Jainism were included but not Hinduism, Confucianism, and Chinese folk religion?

@TheAllMemeingEye Those last three are all a bunch of things.

@EnopoletusHarding and Christianity isn't? There's like dozens and dozens of denominations with very different teachings
