Are sub-$100 Android tablets from brands like PRITOM or generic 2-in-1s any good?

Specialist subreddits like r/androidtablets repeatedly warn that off-brand Android tablets often inflate RAM specs with virtual memory, ship with poor Wi-Fi, slow processors and limited software support. They can work as a casual kids' or kitchen tablet, but reviewers consistently steer shoppers toward a Samsung A-series or Lenovo Tab for anything beyond very light use.
