Most review sites have a profit incentive that doesn't care about the quality of review. But I'll call out a couple that put in effort to be trusted.
Consumer Reports does independent testing with their established criteria. But it's a paid service and doesn't do user submitted reviews.
Steam gets gamed with review bombs but provides plenty of transparency and data for people to make informed decisions. They identify recent review biases and show spikes in volume. Importantly Steam has a generous refund policy with little friction, so they have a profit incentive to match you to a game you want to keep.
