I personally find Ibn Kathir's book more authentic because of his stature and how several ahadiths are narrated and/or collected by him.He also mentions gradation of hadith where he feels suitable.
There is no harm in reading them but always take them with a grain of salt,not as an article of faith.
Hope it helps.
