Poll - Tuned radio frequency receivers or Superheterodyne type receivers?!

Answers: I hope this makes absolutely no sense...
This is easy because EVERYONE knows that Tuned radio frequency (TRF) receivers suffer from poor selectivity and that Supersonic heterodyne receivers (full name) are used in radio and television receivers and transmitters in order to tune them to a particular frequency.
