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

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

But in 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.
