Why Krishna not praised to the level of Rama in respect of Dharma in the Epics/puranas?

Krishna came to earth to destroy evils. Krishna showed that He is from heaven and God vishnu. Rama from the beginning to end acted like a human and never showed that he is mahavishnu. He put every step clearly a way to people. so, people praised him. But, krishna was not praised by many except a few benefitted.
