Obviously Gaudiyas would rank the Bhagavatam first for its statement "Krishnastu Bhagavan swayam".
Ramanuja gave great importance to Vishnu Purana, but apparently never cited the Bhagavatam.
Do the teachers from different sects explain their ranking of the Vaishnavite Puranas?
note: this is obvioulsy not an opinion-based question. An example of what I am asking for is Ramanuja's supreme praise of Vishnu Purana in relation to other Puranas.
