It is considered bad to compare the gods with each other. Each Hindu god has its own powers and is excellent in its field. Still, it would be interesting to know who is the most powerful god is in Hinduism.

There are three main gods in Hinduism, viz. Brahma, Vishnu, and Shiva. These three gods are considered more powerful than all other gods. Hence, according to Hindu mythology, Lord Dattatreya, a combination of those three gods, is termed the most powerful god.

But in the Bhagavad Gita, Lord Krishna says that he is the most powerful of all, and you do not need to worship other deities. Vaishnavaites believe that Lord Krishna is the incarnation of Parmeshwar, i.e., Almighty or Om. Bhagavad-Gita is an extract of the Vedas and all other Hindu scriptures and is the most popular of all. Therefore, we can say that Lord Krishna is the most powerful god in Hinduism.
