whats the difference between Hinduism, taoism, Confucianism and buddhism?

Which one is better and why is purely a matter of personal opinion based on each individuals’ research and life experiences. You’ll have to make up your own mind.
One main difference is that Hinduism has a God/Gods.
Buddhism has no god. I don’t think Taoism or Confucianism do either.
Beyond that, the differences are too numerous to name. And you’ll have to do your own research.

No such thing as a “better” religion… it’s a matter of personal choice.
It’s really hard to put one theology in a nut shell, let alone four of them… but check out beliefnet.com and put them into the search bar. Many good articles will show up.

There are very different, no one is going to take to the time to describe every difference between these religions when you could easily find the differences online. Imo atheistic Hinduism (Hinduism with Gods and sometimes without karma) is the “best” because it is the religion would make the most sense if spirits existed. I seriously doubt the existence of spirits though. (I’m an agnostic btw)

You seriously want an answer to that in the space of a few short paragraphs?
They’re all spelled differently.

Confucianism is a philosophy emphasizing in good moral characters in one’s conduct toward others: from the family, to other people, and ultimately to the country. Therefore Confucius teaching is suitable from kindergartners, students in many levels: politicians, parents, workers, merchants, to empire. The study of Confucianism was required to pass written examination for government posts in many dynasties of China. Confucius attempted to convince the empires to execute peaceful ruling over the citizens as to prevent war and killings. Confucius continued to learn to gain new knowledge, while he had many students and was famous.

In the first 3 sections in the Zhuan Falun on the internet, you can find out a concise discussion about Buddhism. In section, “Buddhist Qigong and Buddhism”, you can read up on its reform, development and its relationship to Hinduism.
High level Daoist practice is summarized on the bottom of page #8 in the Lecture; low level is mentioned on page #105. Other Daoist practice is discussed throughout the book. In addition, there are also martial artists in Tai-chi Chuan and Ba Gua Chuan, relatetd to the Daoist belief.
Not relating to Buddhism nor Daoism, Falun Gong is a unique school, combining the Daoist and Buddhist practice. Falun Gong was found in 1992 by Master Li Hongzhi in China. About 100 million followers like the practice in over 80 countries worldwide. Falun Gong is an ancient practice for the body, mind, and spirit based upon the universal principles of Truthfulness, Compassion, and Tolerance. Falun Gong consists of five sets of powerful exercises.
Falun Gong, Tibetans, other Buddhists, and Daoists have been persecuted in China. The most offensive human right violation is the organ harvesting from the Falun Gong practitioners in China. Can you kindly sign a petition to stop persecution of Falun Gong practitioners in China, please ?
