Okay, you can say which 5 religions you consider best. Here, I made a list of 5 religions with most followers and placed them in a tier list.
1. Islam
2. Sanatana Dharma - Hinduism
3. Buddhism, Taoism, Confucianism
4. Judaism
5. Christianity
So Islam takes 1st place because muslims in many countries are respecting the natural laws (marriage, polygamy, early marriages...) and have higher birth rates than anyone else. While it is true that there are muslim countries which turned different and basically abandoned the natural law, still many muslim countries maintain natural laws more than any other religion does. Muslims also fight to maintain the natural law.
Second place goes to Hinduism and Sanatana Dharma.
Hinduism understands that there is "an eternal law" called Sanatana Dharma (Eternal Dharma). In this way, they understand the basic knowledge that world does have its own eternal moral laws which if followed or if not followed, produce different consequences for the person, good and bad consequences. In this way, Hinduism understands that desirable action can have undesirable consequences, and likewise, undesirable action can have desirable consequences. Thus, the ideal action is desirable action with desirable consequences, hence the Dharma and Karma. Hinduism isnt all about peace. It even has Goddess of destruction Kali. However, their reproduction isnt as good as is in Islam.
3rd place is taken by 3 religions which I really consider to be just one religion with 3 different parts. The reason why they take 3rd place is: while they too understood that there is "eternal natural law", they had horrible misrepresentation of the natural law. Basically, they took the opposite side of natural law. Instead of fighting to survive and multiply, they very much promoted "going with the flow" and just endure whatever punches you. This is like saying "You need to survive and reproduce in order to survive and reproduce", and these 3 say "I understand all that, but I wont try much to achieve it".
The 4th place goes to Judaism. Judaism has no understanding of eternal natural law, but they still maintain decent birth rates, even if declining over time.
5th place goes to Christianity. Christianity has no understanding of eternal natural law. But to make matters worse, its birth rates are also terrible. They abandoned their traditions and today they go in a way which no Christian went before, and even invent a new Christian morality which is more like adding to the Bible than learning from it. Really, almost all Christian countries are going through complete failure of marriage system. They would maybe be better than Judaism if they didnt abandon their own religion and invent new morality which blatantly contradicts the New Testament. Christians are gathering material wealth and making themselves rich when New Testament says that wealth makes it harder to enter heaven, but this was an inevitable consequence of Christian teachings. Christianity doesnt give you anything to think about, as its teachings arent based in any logic but just repeating what the Bible says, which is why spiritual world died in Christianity and was replaced by material world. Everything in Christianity is material. All good deeds are presented as material deeds. It is not a religion which focuses on growing knowledge, dreams and kind word, but just hating your body and your wishes and replacing them with material world.
