Has there been any denigration of some sheikhs (Said ibn Musfir, A'id al-Qarni, Yusuf al-Qaradawi), advising against listening to them or reading their books, from scholars such as Al-Albani and Ibn Baz or others?

Those mentioned in the question are known for their religiosity, knowledge, and call to Allah, and there is no significant disparagement against them. They are human beings who are right at times and wrong at others, so the truth should be accepted from them, and errors respectfully refuted, along with praying for them and finding excuses for them. The advice of Sheikh Ibn Baz regarding those who speak ill of scholars and callers to Allah has already been explained.
