Hinduism isn't the best source for information about Gods character or conduct (certain streams of christianity probably are, though in the vast corpus of Hinduism there are definitely stories about God that rival Christs virtues). also ironically Hinduism is a poor source for information about divine law/dharma (esp compared to the other indian religions which shun casteism, the dharma sutras/shastras were written by brahmins for brahmins and are very casteist. hinduism has a sexism problem too) with the notable exception of its (shared with other indian religions) frequent emphasis on nonviolence, especially uniquely (in world religions) towards animals. furthermore the religion of most of the vedas is not ideal, being so focused on performing often violent sacrifices for and hymning the virtues of the devas instead of extolling/expounding upon Brahman or providing insight into yoga or tantra. the system of sacrifice of the vedas is also quite transactional, it is not nishkama karma. and while one seldom finds a purva-mimamsakan today, the puranas which arguably dominate modern hinduism are also flawed. the "greatest purana", the srimad bhagavatam, has literally thousands of examples of sati.

with all that being said, Hinduism has a monopoly on a supreme truth which is the panentheist monist nature of God, non-dual absolute existence/truth/goodness, consciousness/knowledge, and bliss. hinduism also innovated another truth which is karma and the transmigration of the soul, both key vindications of Gods justice. but probably most importantly, Hinduism has the most developed science of liberation (God realization) of any religion, originating karma yoga in the bhagavad gita, having the most developed brahma-vidya (jnana yoga) of any religion, having the advanced meditative techniques of raja, hatha, and laya yoga, and also having greatly developed (prema)-Bhakti to the high point of any great saint-producing religion.
