Bhagavatam is about the Lord, as told by His Devotees!

1.4.9: Srimad Bhagvatam is full of stories about devotees. Krishna tells in Bhagavad-gita how to attain perfection of life and go back home back to godhead. So here Krishna speaks about Himself less. Whereas in Bhagavatam, it is explained how devotees attain this perfection and also the devotees speak about Krishna here.

So this SB is a wish-fulfilling tree and it is the ripened fruit of Vedic literature, more so it is coming from Srila Sukadeva Goswami, like a fruit tasted by a parrot, even more nice.

One story being told here: Maharaj Parikshit, how he was saved by the Lord, how wonderfully he ruled, how he checked Kali personified. Knowing that one good point is present (chanting of the Holy Name) in Kaliyuga, he allowed Kali. Finally he was cursed to die and even then it is seen how very well he took it. How one should die was shown by Maharaj Parikshit. He heard SB for all 7 days and nights. He protected the weak, dharma, raised everyone's consciousness and finally went back to the spiritual world, actually before the takshaka came to bite him, he was already liberated from the cycle of birth and death.
